zlascl2: performs a diagonal scaling on a vector

NAME

ZLASCL2 - performs a diagonal scaling on a vector

SYNOPSIS

SUBROUTINE ZLASCL2
( M, N, D, X, LDX )

    
IMPLICIT NONE

    
INTEGER M, N, LDX

    
DOUBLE PRECISION D( * )

    
COMPLEX*16 X( LDX, * )

PURPOSE

ZLASCL2 performs a diagonal scaling on a vector:
  <-- 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 standard.

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.
