copy() [1/4]

void copy	(	ConstComplexIterator1D	origin,

Copy data between begin and end to target.

Target must be a valid area of memory. Note that the strides in the iterators can be different, so that we can for example copy data between different kinds of subvectors.

copy() [3/4]

void copy	(	ConstComplexIterator2D	origin,

Copy data between begin and end to target.

Target must be a valid area of memory. Note that the strides in the iterators can be different, so that we can for example copy data between different kinds of subvectors.

Origin, end, and target are 2D iterators, marking rows in a matrix. For each row the 1D iterator is obtained and used to copy the elements.

Matrix-Vector Multiplication.

Uses the Eigen library. Be carful to test the size of your input beforehand.

For left-hand multiplication, please use pure matrix-mult.

Parameters

[out]	y	The length-m ComplexVectorView where the result is stored.
[in]	M	Reference to the m-times-n Const{Complex,}MatrixView holding the matrix M.
[in]	x	Reference to the length-n Const{Complex,}VectorView holding the vector x.

mult() [2/5]

void mult	(	ComplexMatrixView	A,
		const ConstComplexMatrixView &	B,
		const ConstComplexMatrixView &	C
	)

Matrix-Matrix Multiplication.

Uses the Eigen library. Be carful to test the size of your input beforehand. Note that to keep speed, the inputs should be different variables. There is memory duplication if this is not the case. Note that it is mdata that is checked, so even if the matrices are at different parts of a tensor, there is still a slowdown

Parameters

[in,out]	A	The matrix A, that will hold the result of the multiplication.
[in]	B	The matrix B
[in]	C	The matrix C

operator<<() [2/2]

std::ostream& operator<<	(	std::ostream &	os,
		const ConstComplexMatrixView &	v
	)

Output operator.

This demonstrates how iterators can be used to traverse the matrix. The iterators know which part of the matrix is `active', and also the strides in both directions. This function is a bit more complicated than necessary to illustrate the concept, because the formating should look nice. This means that the first row, and the first element in each row, have to be treated individually.
