NAME

       LAPACK-3 - 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:
          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.

ARGUMENTS

        M       (input) INTEGER
                The number of rows of D and X. M >= 0.

        N       (input) INTEGER
                The number of columns of D and X. N >= 0.

        D       (input) DOUBLE PRECISION array, length M
                Diagonal matrix D, stored as a vector of length M.

        X       (input/output) COMPLEX*16 array, dimension (LDX,N)
                On entry, the vector X to be scaled by D.
                On exit, the scaled vector.

        LDX     (input) INTEGER
                The leading dimension of the vector X. LDX >= 0.
