Detailed Description
template<int SizeAtCompileTime, int MaxSizeAtCompileTime, typename IndexType>
class PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >
Permutation matrix.
- 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. IndexType the interger type of the indices
This class represents a permutation matrix, internally stored as a vector of integers.

- class PermutationBase, class PermutationWrapper, class DiagonalMatrix

Definition at line 304 of file PermutationMatrix.h.
| PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >::PermutationMatrix | ( | int | size | ) | [inline] |

| PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >::PermutationMatrix | ( | const PermutationBase< OtherDerived > & | other | ) | [inline] |
Copy constructor.

| PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >::PermutationMatrix | ( | const PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType > & | other | ) | [inline] |
Standard copy constructor. Defined only to prevent a default copy constructor from hiding the other templated constructor
Definition at line 320 of file PermutationMatrix.h.
| PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >::PermutationMatrix | ( | const MatrixBase< Other > & | indices | ) | [inline, explicit] |
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.
