NAME
CLARSCL2  performs a reciprocal diagonal scaling on an vector
SYNOPSIS
 SUBROUTINE CLARSCL2

( M, N, D, X, LDX )

IMPLICIT
NONE

INTEGER
M, N, LDX

COMPLEX
X( LDX, * )

REAL
D( * )
PURPOSE
CLARSCL2 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
standard.
ARGUMENTS
The size of the vectors X and D.
 D (input) REAL array, length N

Diagonal matrix D, stored as a vector of length N.
X (input/output) COMPLEX array, length N
On entry, the vector X to be scaled by D.
On exit, the scaled vector.
