addBottom()

template<typename MatrixType1 , typename MatrixType2 >

void addBottom	(	const MatrixType1 &	Min,
		MatrixType2 &	Mout
	)

Conglutinates two matrices by adding to the bottom. Columns must match or one of the two has to be empty.

Note

Two template parameters are needed in order insert a scaled matrix, which makes a different type in Eigen.

Parameters

Min	: matrix to be added
Mout	: matrix written to

If Mout empty, set Min = Mout

If Min also empty, do nothing.

Definition at line 83 of file DmrgConglutinations.h.

addBottom_makeSquare()

template<typename MatrixType1 , typename MatrixType2 >

void addBottom_makeSquare	(	const MatrixType1 &	Min,
		MatrixType2 &	Mout
	)

If Mout empty, set Min = Mout

If Min also empty, do nothing.

Definition at line 107 of file DmrgConglutinations.h.

addBottomRight()

template<typename MatrixType1 , typename MatrixType2 >

void addBottomRight	(	const MatrixType1 &	Min,
		MatrixType2 &	Mout
	)

Conglutinates two matrices by applying a direct sum.

Note

Two template parameters are needed in order insert a scaled matrix, which makes a different type in Eigen.

Parameters

Min	: matrix to be added
Mout	: matrix written to

Definition at line 9 of file DmrgConglutinations.h.

addPos()

template<typename MatrixType1 , typename MatrixType2 >

void addPos	(	const MatrixType1 &	Min,
		MatrixType2 &	Mout,
		BLOCK_POSITION	POS
	)

Definition at line 134 of file DmrgConglutinations.h.

addRight()

template<typename MatrixType1 , typename MatrixType2 >

void addRight	(	const MatrixType1 &	Min,
		MatrixType2 &	Mout
	)

Conglutinates two matrices by adding to the right. Rows must match or one of the two has to be empty.

Note

Two template parameters are needed in order insert a scaled matrix, which makes a different type in Eigen.

Parameters

Min	: matrix to be added
Mout	: matrix written to

If Mout empty, set Min = Mout

If Min also empty, do nothing.

Definition at line 29 of file DmrgConglutinations.h.

addRight_makeSquare()

template<typename MatrixType1 , typename MatrixType2 >

void addRight_makeSquare	(	const MatrixType1 &	Min,
		MatrixType2 &	Mout
	)

If Mout empty, set Min = Mout

If Min also empty, do nothing.

Definition at line 53 of file DmrgConglutinations.h.

remove_col()

template<typename MatrixType >

void remove_col	(	size_t	i,
		MatrixType &	M
	)

Removes a column of a matrix. Might be useful to remove zero columns before doing SVD and such.

Parameters

i	: column to be removed
M	: apply to this matrix

Definition at line 146 of file DmrgConglutinations.h.

remove_row()

template<typename MatrixType >

void remove_row	(	size_t	i,
		MatrixType &	M
	)

Removes a row of a matrix. Might be useful to remove zero rows before doing SVD and such.

Parameters

i	: row to be removed
M	: apply to this matrix
