Member Function Documentation

Derived& Eigen::PermutationBase::applyTranspositionOnTheLeft	(	Index	i,
		Index	j
	)		[inline, inherited]

Multiplies *this by the transposition on the left.

Returns:

a reference to *this.

Warning:

This is much slower than applyTranspositionOnTheRight(int,int): this has linear complexity and requires a lot of branching.

See also:

applyTranspositionOnTheRight(int,int)

Definition at line 183 of file Core.

Derived& Eigen::PermutationBase::applyTranspositionOnTheRight	(	Index	i,
		Index	j
	)		[inline, inherited]

Multiplies *this by the transposition on the right.

Returns:

a reference to *this.

This is a fast operation, it only consists in swapping two indices.

applyTranspositionOnTheLeft(int,int)

Definition at line 202 of file Core.

Index Eigen::PermutationBase::cols

(

void

)

const [inline, inherited]

const IndicesType& Eigen::Map< PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >, _PacketAccess >::indices

(

)

const [inline]

const version of indices().

Reimplemented from Eigen::PermutationBase< Map< PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >, _PacketAccess > >.

Transpose<PermutationBase> Eigen::PermutationBase::inverse

(

)

const [inline, inherited]

Returns:

the inverse permutation matrix.

Note:

Definition at line 213 of file Core.

PlainPermutationType Eigen::PermutationBase::operator*

(

const PermutationBase< Other > &

other

)

const [inline, inherited]

Returns:

the product permutation matrix.

Note:

Definition at line 247 of file Core.

PlainPermutationType Eigen::PermutationBase::operator*

(

const Transpose< PermutationBase< Other > > &

other

)

const [inline, inherited]

Returns:

the product of a permutation with another inverse permutation.

Note:

Definition at line 255 of file Core.

template<typename Other >

Map& Eigen::Map< PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >, _PacketAccess >::operator=

(

const PermutationBase< Other > &

other

)

[inline]

Copies the other permutation into *this.

Map& Eigen::Map< PermutationMatrix< SizeAtCompileTime, MaxSizeAtCompileTime, IndexType >, _PacketAccess >::operator=

(

const TranspositionsBase< Other > &

tr

)

[inline]

Assignment from the Transpositions tr.

Definition at line 436 of file Core.

void Eigen::PermutationBase::resize

(

Index

size

)

[inline, inherited]

Resizes to given size.

Definition at line 154 of file Core.

Index Eigen::PermutationBase::rows

(

void

)

const [inline, inherited]

Returns:

the number of rows

Definition at line 120 of file Core.

void Eigen::PermutationBase::setIdentity

(

)

[inline, inherited]

Sets *this to be the identity permutation matrix.

Definition at line 160 of file Core.

void Eigen::PermutationBase::setIdentity

(

Index

)

[inline, inherited]

Sets *this to be the identity permutation matrix of given size.

Definition at line 168 of file Core.

Index Eigen::PermutationBase::size

(

)

const [inline, inherited]

Returns:

the size of a side of the respective square matrix, i.e., the number of indices

Definition at line 126 of file Core.

DenseMatrixType Eigen::PermutationBase::toDenseMatrix

(

)

const [inline, inherited]

Returns:

a Matrix object initialized from this permutation matrix. Notice that it is inefficient to return this Matrix object by value. For efficiency, favor using the Matrix constructor taking EigenBase objects.

Transpose<PermutationBase> Eigen::PermutationBase::transpose

(

)

const [inline, inherited]

Returns:

the tranpose permutation matrix.

Note:
