Member Function Documentation

matmul()

template<class T >

void Ensign::Matrix::blas_ops::matmul	(	const multi_array< T, 2 > &	a,
		const multi_array< T, 2 > &	b,
		multi_array< T, 2 > &	c
	)		const

Matrix multiplication (computes c = a b)

The number of rows in matrix c can be smaller than the number of rows in matrix a. In this case only a partial result is computed.

matmul_transa()

template<class T >

void Ensign::Matrix::blas_ops::matmul_transa	(	const multi_array< T, 2 > &	a,
		const multi_array< T, 2 > &	b,
		multi_array< T, 2 > &	c
	)		const

Matrix multiplication with first matrix transposed (computes c = a^T b)

matmul_transab()

template<class T >

void Ensign::Matrix::blas_ops::matmul_transab	(	const multi_array< T, 2 > &	a,
		const multi_array< T, 2 > &	b,
		multi_array< T, 2 > &	c
	)		const

Matrix multiplication with both matrices transposed (computes c = a^T b^T)

matmul_transb()

template<class T >

void Ensign::Matrix::blas_ops::matmul_transb	(	const multi_array< T, 2 > &	a,
		const multi_array< T, 2 > &	b,
		multi_array< T, 2 > &	c
	)		const

Matrix multiplication with second matrix transposed (computes c = a b^T)

matvec()

template<class T >

void Ensign::Matrix::blas_ops::matvec	(	const multi_array< T, 2 > &	a,
		const multi_array< T, 1 > &	b,
		multi_array< T, 1 > &	c
	)		const

Matrix vector multiplication (c = a b)

matvec_trans()

template<class T >

void Ensign::Matrix::blas_ops::matvec_trans	(	const multi_array< T, 2 > &	a,
		const multi_array< T, 1 > &	b,
		multi_array< T, 1 > &	c
	)		const

Matrix vector multiplication with matrix transposed (c = a^T b)

transpose()

template<class T >

void Ensign::Matrix::blas_ops::transpose	(	const multi_array< T, 2 > &	in,
		multi_array< T, 2 > &	out
	)		const

Transpose a matrix.
