Detailed Description
template<int SizeAtCompileTime, int MaxSizeAtCompileTime, typename _StorageIndex>
class Eigen::PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, _StorageIndex >
Permutation matrix.
- Template Parameters
-
SizeAtCompileTime the number of rows/cols, or Dynamic MaxSizeAtCompileTime the maximum number of rows/cols, or Dynamic. This optional parameter defaults to SizeAtCompileTime. Most of the time, you should not have to specify it. _StorageIndex the integer type of the indices
This class represents a permutation matrix, internally stored as a vector of integers.

Constructor & Destructor Documentation
§ PermutationMatrix() [1/3]
template<int SizeAtCompileTime, int MaxSizeAtCompileTime, typename _StorageIndex>
template<typename OtherDerived >
|
inline |
Copy constructor.
§ PermutationMatrix() [2/3]
template<int SizeAtCompileTime, int MaxSizeAtCompileTime, typename _StorageIndex>
|
inline |
Standard copy constructor.
Defined only to prevent a default copy constructor from hiding the other templated constructor
§ PermutationMatrix() [3/3]
template<int SizeAtCompileTime, int MaxSizeAtCompileTime, typename _StorageIndex>
template<typename Other >
|
inlineexplicit |
Generic constructor from expression of the indices.
The indices array has the meaning that the permutations sends each integer i to indices[i].
- Warning
- It is your responsibility to check that the indices array that you passes actually describes a permutation, i.e., each value between 0 and n-1 occurs exactly once, where n is the array's size.
Member Function Documentation
§ indices() [1/2]
template<int SizeAtCompileTime, int MaxSizeAtCompileTime, typename _StorageIndex>
|
inline |
const version of indices().
§ indices() [2/2]
template<int SizeAtCompileTime, int MaxSizeAtCompileTime, typename _StorageIndex>
|
inline |
- Returns
- a reference to the stored array representing the permutation.
§ operator=()
template<int SizeAtCompileTime, int MaxSizeAtCompileTime, typename _StorageIndex>
|
inline |
This is a special case of the templated operator=.
Its purpose is to prevent a default operator= from hiding the templated operator=.
