subroutine clascl2 (M, N, D, X, LDX)
CLASCL2 performs diagonal scaling on a vector.
CLASCL2 performs diagonal scaling on a vector.
Purpose:
CLASCL2 performs a diagonal scaling on a vector: x <-- D * x where the diagonal REAL matrix D is stored as a vector. Eventually to be replaced by BLAS_cge_diag_scale in the new BLAS standard.
Parameters:
M is INTEGER The number of rows of D and X. M >= 0.
N
N is INTEGER The number of columns of X. N >= 0.
D
D is REAL array, length M Diagonal matrix D, stored as a vector of length M.
X
X is COMPLEX array, dimension (LDX,N) On entry, the vector X to be scaled by D. On exit, the scaled vector.
LDX
LDX is INTEGER The leading dimension of the vector X. LDX >= M.
