Detailed Description

template<int SizeAtCompileTime, int MaxSizeAtCompileTime, typename IndexType>
class Eigen::PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >

Permutation matrix.

Parameters:
SizeAtCompileTimethe number of rows/cols, or Dynamic
MaxSizeAtCompileTimethe maximum number of rows/cols, or Dynamic. This optional parameter defaults to SizeAtCompileTime. Most of the time, you should not have to specify it.
IndexTypethe interger type of the indices

This class represents a permutation matrix, internally stored as a vector of integers.

Constructor & Destructor Documentation

PermutationMatrix ( int  size) [inline]

Constructs an uninitialized permutation matrix of given size.

PermutationMatrix ( const PermutationBase< OtherDerived > &  other) [inline]

Copy constructor.

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.
PermutationMatrix ( const TranspositionsBase< Other > &  tr) [inline, explicit]

Convert the Transpositions tr to a permutation matrix


Member Function Documentation

const IndicesType& indices ( ) const [inline]
IndicesType& indices ( ) [inline]
Returns:
a reference to the stored array representing the permutation.

Reimplemented from PermutationBase< PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType > >.

PermutationMatrix& operator= ( const PermutationBase< Other > &  other) [inline]

Copies the other permutation into *this

PermutationMatrix& operator= ( const TranspositionsBase< Other > &  tr) [inline]

Assignment from the Transpositions tr
