NAME
       SRC/slarscl2.f

SYNOPSIS
   Functions/Subroutines
       subroutine slarscl2 (m, n, d, x, ldx)
           SLARSCL2 performs reciprocal diagonal scaling on a matrix.

Function/Subroutine Documentation
   subroutine slarscl2 (integer m, integer n, real, dimension( * ) d, real,
       dimension( ldx, * ) x, integer ldx)
       SLARSCL2 performs reciprocal diagonal scaling on a matrix.

       Purpose:


            SLARSCL2 performs a reciprocal diagonal scaling on a matrix:
              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.

       Parameters
           M

                     M is INTEGER
                The number of rows of D and X. M >= 0.

           N

                     N is INTEGER
                The number of columns of X. N >= 0.

           D

                     D is REAL array, length M
                Diagonal matrix D, stored as a vector of length M.

           X

                     X is REAL array, dimension (LDX,N)
                On entry, the matrix X to be scaled by D.
                On exit, the scaled matrix.

           LDX

                     LDX is INTEGER
                The leading dimension of the matrix X. LDX >= M.
