Detailed Description

template<typename Derived>
class Eigen::MatrixBase< Derived >

Base class for all dense matrices, vectors, and expressions.

This class is the base that is inherited by all matrix, vector, and related expression types. Most of the Eigen API is contained in this class, and its base classes. Other important classes for the Eigen API are Matrix, and VectorwiseOp.

Note that some methods are defined in other modules such as the LU_Module LU module for all functions related to matrix inversions.

Template Parameters
Derivedis the derived type, e.g. a matrix type, or an expression, etc.

When writing a function taking Eigen objects as argument, if you want your function to take as argument any matrix, vector, or expression, just let it take a MatrixBase argument. As an example, here is a function printFirstRow which, given a matrix, vector, or expression x, prints the first row of x.

template<typename Derived>
void printFirstRow(const Eigen::MatrixBase<Derived>& x)
{
cout << x.row(0) << endl;
}

This class can be extended with the help of the plugin mechanism described on the page Extending MatrixBase (and other classes) by defining the preprocessor symbol EIGEN_MATRIXBASE_PLUGIN.

Member Function Documentation

§ adjoint()

template<typename Derived >
const MatrixBase< Derived >::AdjointReturnType Eigen::MatrixBase< Derived >::adjoint ( ) const
inline
Returns
an expression of the adjoint (i.e. conjugate transpose) of *this.

Example:

Output:

Warning
If you want to replace a matrix by its own adjoint, do NOT do this:
m = m.adjoint(); // bug!!! caused by aliasing effect
Instead, use the adjointInPlace() method:
m.adjointInPlace();
which gives Eigen good opportunities for optimization, or alternatively you can also do:
m = m.adjoint().eval();
See also
adjointInPlace(), transpose(), conjugate(), class Transpose, class internal::scalar_conjugate_op

§ adjointInPlace()

template<typename Derived >
void Eigen::MatrixBase< Derived >::adjointInPlace ( )
inline

This is the "in place" version of adjoint(): it replaces *this by its own transpose.

Thus, doing

m.adjointInPlace();

has the same effect on m as doing

m = m.adjoint().eval();

and is faster and also safer because in the latter line of code, forgetting the eval() results in a bug caused by aliasing.

Notice however that this method is only useful if you want to replace a matrix by its own adjoint. If you just need the adjoint of a matrix, use adjoint().

Note
if the matrix is not square, then *this must be a resizable matrix. This excludes (non-square) fixed-size matrices, block-expressions and maps.
See also
transpose(), adjoint(), transposeInPlace()

§ applyHouseholderOnTheLeft()

template<typename Derived >
template<typename EssentialPart >
void Eigen::MatrixBase< Derived >::applyHouseholderOnTheLeft ( const EssentialPart &  essential,

§ applyHouseholderOnTheRight()

template<typename Derived >
template<typename EssentialPart >
void Eigen::MatrixBase< Derived >::applyHouseholderOnTheRight ( const EssentialPart &  essential,
const Scalar tau,
Scalar workspace 
)

Apply the elementary reflector H given by \( H = I - tau v v^*\) with \( v^T = [1 essential^T] \) from the right to a vector or matrix.

On input:

Parameters
essentialthe essential part of the vector v
tauthe scaling factor of the Householder transformation

§ applyOnTheLeft() [1/2]

template<typename Derived >
template<typename OtherDerived >
void Eigen::MatrixBase< Derived >::applyOnTheLeft ( const EigenBase< OtherDerived > &  other)
inline

replaces *this by other * *this.

Example:

Output:

 

§ applyOnTheLeft() [2/2]

template<typename Derived >
template<typename OtherScalar >
void Eigen::MatrixBase< Derived >::applyOnTheLeft ( Index  p,
Index  q,
const JacobiRotation< OtherScalar > &  j 
)
inline

Applies the rotation in the plane j to the rows p and q of *this, i.e., it computes B = J * B, with \( B = \left ( \begin{array}{cc} \text{*this.row}(p) \\ \text{*this.row}(q) \end{array} \right ) \).

See also
class JacobiRotation, MatrixBase::applyOnTheRight(), internal::apply_rotation_in_the_plane()

§ applyOnTheRight()

template<typename Derived >
template<typename OtherDerived >
void Eigen::MatrixBase< Derived >::applyOnTheRight ( const EigenBase< OtherDerived > &  other)
inline

replaces *this by *this * other.

It is equivalent to MatrixBase::operator*=().

Example:

Output:

 

§ array() [1/2]

template<typename Derived>
EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE ArrayWrapper<Derived> Eigen::MatrixBase< Derived >::array ( )
inline
Returns
an Array expression of this matrix
See also
ArrayBase::matrix()

§ array() [2/2]

template<typename Derived>
EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE const ArrayWrapper<const Derived> Eigen::MatrixBase< Derived >::array ( ) const
inline
Returns
a const Array expression of this matrix
See also
ArrayBase::matrix()

§ asDiagonal()

template<typename Derived >
const DiagonalWrapper< const Derived > Eigen::MatrixBase< Derived >::asDiagonal ( ) const
inline
Returns
a pseudo-expression of a diagonal matrix with *this as vector of diagonal coefficients

Example:

Output:

See also
class DiagonalWrapper, class DiagonalMatrix, diagonal(), isDiagonal()

§ bdcSvd()

template<typename Derived >
BDCSVD< typename MatrixBase< Derived >::PlainObject > Eigen::MatrixBase< Derived >::bdcSvd ( unsigned int  computationOptions = 0) const
inline

Returns
the singular value decomposition of *this computed by Divide & Conquer algorithm
See also
class BDCSVD

§ binaryExpr()

template<typename Derived>
template<typename CustomBinaryOp , typename OtherDerived >
EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE const CwiseBinaryOp<CustomBinaryOp, const Derived, const OtherDerived> Eigen::MatrixBase< Derived >::binaryExpr ( const EIGEN_CURRENT_STORAGE_BASE_CLASS< OtherDerived > &  other,
const CustomBinaryOp &  func = CustomBinaryOp() 
) const
inline
Returns
an expression of the difference of *this and other
Note
If you want to substract a given scalar from all coefficients, see Cwise::operator-().
See also
class CwiseBinaryOp, operator-=()
Returns
an expression of the sum of *this and other
Note
If you want to add a given scalar to all coefficients, see Cwise::operator+().
See also
class CwiseBinaryOp, operator+=()
Returns
an expression of a custom coefficient-wise operator func of *this and other

The template parameter CustomBinaryOp is the type of the functor of the custom operator (see class CwiseBinaryOp for an example)

Here is an example illustrating the use of custom functors:

Output:

See also
class CwiseBinaryOp, operator+(), operator-(), cwiseProduct()

§ blueNorm()

template<typename Derived >
NumTraits< typename internal::traits< Derived >::Scalar >::Real Eigen::MatrixBase< Derived >::blueNorm ( ) const
inline
Returns
the l2 norm of *this using the Blue's algorithm. A Portable Fortran Program to Find the Euclidean Norm of a Vector, ACM TOMS, Vol 4, Issue 1, 1978.

For architecture/scalar types without vectorization, this version is much faster than stableNorm(). Otherwise the stableNorm() is faster.

See also
norm(), stableNorm(), hypotNorm()

§ cast()

template<typename Derived>
template<typename NewType >
EIGEN_DEVICE_FUNC CastXpr<NewType>::Type Eigen::MatrixBase< Derived >::cast ( ) const
inline
Returns
an expression of *this with the Scalar type casted to NewScalar.

The template parameter NewScalar is the type we are casting the scalars to.

The parameters rows and cols are the number of rows and of columns of the returned matrix. Must be compatible with this MatrixBase type.

This variant is meant to be used for dynamic-size matrix types. For fixed-size types, it is redundant to pass rows and cols as arguments, so Identity() should be used instead.

Example:

Output:

 

§ isUpperTriangular()

template<typename Derived >
bool Eigen::MatrixBase< Derived >::isUpperTriangular ( const RealScalar &  prec = NumTraits<Scalar>::dummy_precision()) const

Returns
an expression of the matrix product of *this and other without implicit evaluation.

The returned product will behave like any other expressions: the coefficients of the product will be computed once at a time as requested. This might be useful in some extremely rare cases when only a small and no coherent fraction of the result's coefficients have to be computed.

Warning
This version of the matrix product can be much much slower. So use it only if you know what you are doing and that you measured a true speed improvement.

inline
Returns
the coefficient-wise \( \ell^p \) norm of *this, that is, returns the p-th root of the sum of the p-th powers of the absolute values of the coefficients of *this. If p is the special value Eigen::Infinity, this function returns the \( \ell^\infty \) norm, that is the maximum of the absolute values of the coefficients of *this.

In all cases, if *this is empty, then the value 0 is returned.

Note
For matrices, this function does not compute the operator-norm. That is, if *this is a matrix, then its coefficients are interpreted as a 1D vector. Nonetheless, you can easily compute the 1-norm and \(\infty\)-norm matrix operator norms using partial reductions .

§ noalias()

template<typename Derived >
NoAlias< Derived, MatrixBase > Eigen::MatrixBase< Derived >::noalias ( )
Returns
a pseudo expression of *this with an operator= assuming no aliasing between *this and the source expression.

More precisely, noalias() allows to bypass the EvalBeforeAssignBit flag. Currently, even though several expressions may alias, only product expressions have this flag. Therefore, noalias() is only usefull when the source expression contains a matrix product.

Here are some examples where noalias is usefull:

D.noalias() = A * B;
D.noalias() += A.transpose() * B;
D.noalias() -= 2 * A * B.adjoint();

On the other hand the following example will lead to a wrong result:

A.noalias() = A * B;

because the result matrix A is also an operand of the matrix product. Therefore, there is no alternative than evaluating A * B in a temporary, that is the default behavior when you write:

A = A * B;
See also
class NoAlias

template<typename Derived >
const MatrixBase< Derived >::PlainObject Eigen::MatrixBase< Derived >::normalized ( ) const

§ operatorNorm()

template<typename Derived >
MatrixBase< Derived >::RealScalar Eigen::MatrixBase< Derived >::operatorNorm ( ) const
inline

Computes the L2 operator norm.

Returns
Operator norm of the matrix.

This function computes the L2 operator norm of a matrix, which is also known as the spectral norm. The norm of a matrix \( A \) is defined to be

\[ \|A\|_2 = \max_x \frac{\|Ax\|_2}{\|x\|_2} \]

where the maximum is over all vectors and the norm on the right is the Euclidean vector norm. The norm equals the largest singular value, which is the square root of the largest eigenvalue of the positive semi-definite matrix \( A^*A \).

The current implementation uses the eigenvalues of \( A^*A \), as computed by SelfAdjointView::eigenvalues(), to compute the operator norm of a matrix. The SelfAdjointView class provides a better algorithm for selfadjoint matrices.

§ squaredNorm()

template<typename Derived >
EIGEN_STRONG_INLINE NumTraits< typename internal::traits< Derived >::Scalar >::Real Eigen::MatrixBase< Derived >::squaredNorm ( ) const
Returns
, for vectors, the squared l2 norm of *this, and for matrices the Frobenius norm. In both cases, it consists in the sum of the square of all the matrix entries. For vectors, this is also equals to the dot product of *this with itself.
See also
dot(), norm(), lpNorm()

§ stableNorm()

template<typename Derived >
NumTraits< typename internal::traits< Derived >::Scalar >::Real Eigen::MatrixBase< Derived >::stableNorm ( ) const
inline
Returns
the l2 norm of *this avoiding underflow and overflow. This version use a blockwise two passes algorithm: 1 - find the absolute largest coefficient s 2 - compute \( s \Vert \frac{*this}{s} \Vert \) in a standard way

For architecture/scalar types supporting vectorization, this version is faster than blueNorm(). Otherwise the blueNorm() is much faster.

norm(), blueNorm(), hypotNorm()

§ stableNormalize()

template<typename Derived >
void Eigen::MatrixBase< Derived >::stableNormalize ( )
inline

Normalizes the vector while avoid underflow and overflow.

This method is analogue to the normalize() method, but it reduces the risk of underflow and overflow when computing the norm.

Warning
If the input vector is too small (i.e., this->norm()==0), then *this is left unchanged.
See also
stableNorm(), stableNormalized(), normalize()

§ stableNormalized()

template<typename Derived >
const MatrixBase< Derived >::PlainObject Eigen::MatrixBase< Derived >::stableNormalized ( ) const
inline
Returns
an expression of the quotient of *this by its own norm while avoiding underflow and overflow.

This method is analogue to the normalized() method, but it reduces the risk of underflow and overflow when computing the norm.

Warning
If the input vector is too small (i.e., this->norm()==0), then this function returns a copy of the input.

stableNorm(), stableNormalize(), normalized()

§ trace()

template<typename Derived >
EIGEN_STRONG_INLINE internal::traits< Derived >::Scalar Eigen::MatrixBase< Derived >::trace ( ) const
Returns
the trace of *this, i.e. the sum of the coefficients on the main diagonal.

*this can be any matrix, not necessarily square.
