CLASCL multiplies the M by N complex matrix A by the real scalar CTO/CFROM.

This is done without over/underflow as long as the final result CTO*A(I,J)/CFROM does not over/underflow. TYPE specifies that A may be full, upper triangular, lower triangular.

Parameters

[in]	type	magma_type_t TYPE indices the storage type of the input matrix A. = MagmaFull: full matrix. = MagmaLower: lower triangular matrix. = MagmaUpper: upper triangular matrix. Other formats that LAPACK supports, MAGMA does not currently support.
[in]	kl	INTEGER Unused, for LAPACK compatability.
[in]	ku	KU is INTEGER Unused, for LAPACK compatability.
[in]	cfrom	REAL
[in]	cto	REAL The matrix A is multiplied by CTO/CFROM. A(I,J) is computed without over/underflow if the final result CTO*A(I,J)/CFROM can be represented without over/underflow. CFROM must be nonzero. CFROM and CTO must not be NAN.
[in]	m	INTEGER The number of rows of the matrix A. M >= 0.
[in]	n	INTEGER The number of columns of the matrix A. N >= 0.
[in,out]	dA	COMPLEX array, dimension (LDDA,N) The matrix to be multiplied by CTO/CFROM. See TYPE for the storage type.
[in]	ldda	INTEGER The leading dimension of the array A. LDDA >= max(1,M).
[out]	info	INTEGER = 0: successful exit < 0: if INFO = -i, the i-th argument had an illegal value.
[in]	queue	magma_queue_t Queue to execute in.
