NAME

       LAPACK-3 - performs a diagonal scaling on a vector

SYNOPSIS

       SUBROUTINE CLASCL2 ( M, N, D, X, LDX )

           IMPLICIT       NONE

           INTEGER        M, N, LDX

           REAL           D( * )

           COMPLEX        X( LDX, * )

PURPOSE

       CLASCL2 performs a diagonal scaling on a vector:
          x <-- D * x
        where the diagonal REAL matrix D is stored as a vector.
        Eventually to be replaced by BLAS_cge_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) REAL array, length M
                Diagonal matrix D, stored as a vector of length M.

        X       (input/output) COMPLEX 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.
