Detailed Description

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

Base class of any sparse matrices or sparse expressions.

Template Parameters

Derived is the derived type, e.g. a sparse matrix type, or an expression, etc.

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_SPARSEMATRIXBASE_PLUGIN.

Member Typedef Documentation

§ RealScalar

template<typename Derived>

typedef NumTraits<Scalar>::Real Eigen::SparseMatrixBase< Derived >::RealScalar

This is the "real scalar" type; if the Scalar type is already real numbers (e.g.

int, float or double) then RealScalar is just the same as Scalar. If Scalar is std::complex<T> then RealScalar is T.

See also: class NumTraits

§ value_type

template<typename Derived>

typedef Scalar Eigen::SparseMatrixBase< Derived >::value_type

The numeric type of the expression' coefficients, e.g.

float, double, int or std::complex<float>, etc.

It is an alias for the Scalar type

Member Enumeration Documentation

§ anonymous enum

template<typename Derived>

anonymous enum

Enumerator
RowsAtCompileTime	The number of rows at compile-time. This is just a copy of the value provided by the Derived type. If a value is not known at compile-time, it is set to the Dynamic constant. See also MatrixBase::rows(), MatrixBase::cols(), ColsAtCompileTime, SizeAtCompileTime
ColsAtCompileTime	The number of columns at compile-time. This is just a copy of the value provided by the Derived type. If a value is not known at compile-time, it is set to the Dynamic constant. See also MatrixBase::rows(), MatrixBase::cols(), RowsAtCompileTime, SizeAtCompileTime
SizeAtCompileTime	This is equal to the number of coefficients, i.e. the number of rows times the number of columns, or to Dynamic if this is not known at compile-time. See also RowsAtCompileTime, ColsAtCompileTime
IsVectorAtCompileTime	This is set to true if either the number of rows or the number of columns is known at compile-time to be equal to 1. Indeed, in that case, we are dealing with a column-vector (if there is only one column) or with a row-vector (if there is only one row).
Flags	This stores expression Flags flags which may or may not be inherited by new expressions constructed from this one. See the list of flags.

§ binaryExpr()

template<typename Derived>

template<typename CustomBinaryOp , typename OtherDerived >

EIGEN_DEVICE_FUNC EIGEN_STRONG_INLINE const CwiseBinaryOp<CustomBinaryOp, const Derived, const OtherDerived> Eigen::SparseMatrixBase< 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:

cRows	the number of rows in the corner
cCols	the number of columns in the corner

Example:

Output:

class Block, block(Index,Index,Index,Index)

§ topLeftCorner() [2/3]

template<typename Derived>

template<int CRows, int CCols>

EIGEN_DOC_BLOCK_ADDONS_NOT_INNER_PANEL EIGEN_DEVICE_FUNC FixedBlockXpr<CRows,CCols>::Type Eigen::SparseMatrixBase< Derived >::topLeftCorner ( )

inline

Returns: an expression of a fixed-size top-left corner of *this.

The template parameters CRows and CCols are the number of rows and columns in the corner.

Example:

Output:

class Block, block(Index,Index,Index,Index)

§ topLeftCorner() [3/3]

template<typename Derived>

template<int CRows, int CCols>

EIGEN_DOC_BLOCK_ADDONS_NOT_INNER_PANEL FixedBlockXpr<CRows,CCols>::Type Eigen::SparseMatrixBase< Derived >::topLeftCorner	(	Index	cRows,
		Index	cCols
	)

inline

Returns: an expression of a top-left corner of *this.

Template Parameters

CRows	number of rows in corner as specified at compile-time
CCols	number of columns in corner as specified at compile-time

Parameters

cRows	number of rows in corner as specified at run-time
cCols	number of columns in corner as specified at run-time

This function is mainly useful for corners where the number of rows is specified at compile-time and the number of columns is specified at run-time, or vice versa. The compile-time and run-time information should not contradict. In other words, cRows should equal CRows unless CRows is Dynamic, and the same for the number of columns.

Example:

Output:

class Block

§ topRightCorner() [1/3]

		Index	cCols
	)

inline

Returns: a dynamic-size expression of a top-right corner of *this.

Parameters

cRows	the number of rows in the corner
cCols	the number of columns in the corner

Example:

Output:

class Block, block(Index,Index,Index,Index)

§ topRightCorner() [2/3]

template<typename Derived>

template<int CRows, int CCols>

EIGEN_DOC_BLOCK_ADDONS_NOT_INNER_PANEL EIGEN_DEVICE_FUNC FixedBlockXpr<CRows,CCols>::Type Eigen::SparseMatrixBase< Derived >::topRightCorner ( )

inline

Returns: an expression of a fixed-size top-right corner of *this.

Template Parameters

CRows	the number of rows in the corner
CCols	the number of columns in the corner

Example:

Output:

class Block, block<int,int>(Index,Index)

§ topRightCorner() [3/3]

template<typename Derived>

template<int CRows, int CCols>

EIGEN_DOC_BLOCK_ADDONS_NOT_INNER_PANEL FixedBlockXpr<CRows,CCols>::Type Eigen::SparseMatrixBase< Derived >::topRightCorner	(	Index	cRows,
		Index	cCols
	)

inline

Returns: an expression of a top-right corner of *this.

Template Parameters

CRows	number of rows in corner as specified at compile-time
CCols	number of columns in corner as specified at compile-time

Parameters

cRows	number of rows in corner as specified at run-time
cCols	number of columns in corner as specified at run-time

This function is mainly useful for corners where the number of rows is specified at compile-time and the number of columns is specified at run-time, or vice versa. The compile-time and run-time information should not contradict. In other words, cRows should equal CRows unless CRows is Dynamic, and the same for the number of columns.

Example:

Output:

class Block

§ topRows() [1/2]

template<typename Derived>

EIGEN_DEVICE_FUNC RowsBlockXpr Eigen::SparseMatrixBase< Derived >::topRows ( Index n )

inline

Returns: a block consisting of the top rows of *this.

Parameters

n	the number of rows in the block

Example:

Output:

class Block, block(Index,Index,Index,Index)

§ topRows() [2/2]

template<typename Derived>

template<int N>

EIGEN_DEVICE_FUNC NRowsBlockXpr<N>::Type Eigen::SparseMatrixBase< Derived >::topRows ( Index n = N )

inline

Returns: a block consisting of the top rows of *this.

Template Parameters

N	the number of rows in the block as specified at compile-time

Parameters

n	the number of rows in the block as specified at run-time

The compile-time and run-time information should not contradict. In other words, n should equal N unless N is Dynamic.

Example:

Output:

class Block, block(Index,Index,Index,Index)

§ twistedBy()

template<typename Derived>

SparseSymmetricPermutationProduct<Derived,Upper|Lower> Eigen::SparseMatrixBase< Derived >::twistedBy ( const PermutationMatrix< Dynamic, Dynamic, StorageIndex > & perm ) const

inline

Returns: an expression of P H P^-1 where H is the matrix represented by *this

§ unaryExpr()

template<typename Derived>

template<typename CustomUnaryOp >

EIGEN_DEVICE_FUNC const CwiseUnaryOp<CustomUnaryOp, const Derived> Eigen::SparseMatrixBase< Derived >::unaryExpr ( const CustomUnaryOp & func = CustomUnaryOp() ) const

inline

Apply a unary operator coefficient-wise.

Parameters

[in] func Functor implementing the unary operator

Template Parameters

CustomUnaryOp Type of func

Returns: An expression of a custom coefficient-wise unary operator func of *this

The function ptr_fun() from the C++ standard library can be used to make functors out of normal functions.

Example:

Output:

Genuine functors allow for more possibilities, for instance it may contain a state.

Example:

Output:

See also: unaryViewExpr, binaryExpr, class CwiseUnaryOp

§ unaryViewExpr()

The template parameter CustomUnaryOp is the type of the functor of the custom unary operator.

Example:

Output:

unaryExpr, binaryExpr class CwiseUnaryOp
