ZLARSCL2(1)LAPACK routine (version 3.2) ZLARSCL2(1)NAME
ZLARSCL2 - performs a reciprocal diagonal scaling on an vector
SYNOPSIS
SUBROUTINE ZLARSCL2 ( M, N, D, X, LDX )
IMPLICIT NONE
INTEGER M, N, LDX
COMPLEX*16 X( LDX, * )
DOUBLE PRECISION D( * )
PURPOSE
ZLARSCL2 performs a reciprocal diagonal scaling on an vector:
x <-- inv(D) * x
where the diagonal matrix D is stored as a vector.
Eventually to be replaced by BLAS_sge_diag_scale in the new BLAS stan‐
dard.
ARGUMENTS
The size of the vectors X and D.
D (input) DOUBLE PRECISION array, length N
Diagonal matrix D, stored as a vector of length N. X
(input/output) COMPLEX*16 array, length N On entry, the vector X
to be scaled by D. On exit, the scaled vector.
