		double *	A,
		int	LDA
	)

PLASMA_dlascal - Scales a matrix by the scalar alpha as in ScaLAPACK pdlascal().

\[ A = \alpha A \]

,

alpha is a scalar, and A a general, upper or lower trapezoidal matrix.

Parameters

[in]	uplo	Specifies the shape of A: = PlasmaUpperLower: A is a general matrix. = PlasmaUpper: A is an upper trapezoidal matrix. = PlasmaLower: A is a lower trapezoidal matrix.
[in]	M	M specifies the number of rows of the matrix A. M >= 0.
[in]	N	N specifies the number of columns of the matrix A. N >= 0.
[in]	alpha	alpha specifies the scalar alpha
[in,out]	A	A is a LDA-by-N matrix.
[in]	LDA	The leading dimension of the array A. LDA >= max(1,M).
