Function Documentation

void CORE_dlaset2	(	PLASMA_enum	uplo,
		int	M,
		int	N,
		double	alpha,
		double *	A,
		int	LDA
	)

CORE_dlaset2 - Sets the elements of the matrix A to alpha. Not LAPACK compliant! Read below.

Parameters:

[in]	uplo	Specifies which elements of the matrix are to be set = PlasmaUpper: STRICT Upper part of A is set to alpha; = PlasmaLower: STRICT Lower part of A is set to alpha; = PlasmaUpperLower: ALL elements of A are set to alpha. Not LAPACK Compliant.
[in]	M	The number of rows of the matrix A. M >= 0.
[in]	N	The number of columns of the matrix A. N >= 0.
[in]	alpha	The constant to which the elements are to be set.
[in,out]	A	On entry, the M-by-N tile A. On exit, A has been set to alpha accordingly.
[in]	LDA	The leading dimension of the array A. LDA >= max(1,M).
