SYNOPSIS
Functions/Subroutines
subroutine zlascl2 (M, N, D, X, LDX)
ZLASCL2 performs diagonal scaling on a vector.
Function/Subroutine Documentation
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.
Parameters:
M
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.
