Function Documentation

ytMatrix_dsytrf_work_size()

int ytMatrix_dsytrf_work_size

(

int

n

)

Returns the optimal working memory size for dsytrf routine.

Returns

optimal working memory size used by SGN_Matrix_dsytrf(), or 0 if the native LAPACK routine does not need it.

ytMatrix_print()

void ytMatrix_print	(	FILE *	fp,
		const double *	X,
		int	m,
		int	n,
		int	N )

Prints the matrix.

Parameters

fp
X
m
n
N

ytMatrix_printTrans()

void ytMatrix_printTrans	(	FILE *	fp,
		const double *	X,
		int	m,
		int	n,
		int	N )

Prints the transposed or row-major matrix.

Parameters

fp
X
m
n
N

ytMatrix_trace()

double ytMatrix_trace	(	const int	n,
		const int	m,
		double *	X )

Returns the trace of the given matrix.

The trace of a matrix is the sum of diagonal elements of the matrix.
