subroutine zlascl2 (M, N, D, X, LDX)
subroutine zlascl2 (integerM, integerN, double precision, dimension( * )D, complex*16, dimension( ldx, * )X, integerLDX)ZLASCL2 performs diagonal scaling on a vector. Purpose:
ZLASCL2 performs a diagonal scaling on a vector: x <-- D * x where the DOUBLE PRECISION diagonal matrix D is stored as a vector. Eventually to be replaced by BLAS_zge_diag_scale in the new BLAS standard.
M is INTEGER The number of rows of D and X. M >= 0.N
N is INTEGER The number of columns of D and X. N >= 0.D
D is DOUBLE PRECISION array, length M Diagonal matrix D, stored as a vector of length M.X
X is COMPLEX*16 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 >= 0.
