   Functions/Subroutines
       subroutine dlarscl2 (M, N, D, X, LDX)
           DLARSCL2 performs reciprocal diagonal scaling on a vector.

Function/Subroutine Documentation

   subroutine dlarscl2 (integer M, integer N, double precision, dimension( * ) D, double precision, dimension(
       ldx, * ) X, integer LDX)
       DLARSCL2 performs reciprocal diagonal scaling on a vector.

       Purpose:

            DLARSCL2 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_dge_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 DOUBLE PRECISION array, dimension (M)
                Diagonal matrix D, stored as a vector of length M.

           X

                     X is DOUBLE PRECISION array, dimension (LDX,N)
                On entry, the vector X to be scaled by D.
                On exit, the scaled vector.

           LDX

                     LDX is INTEGER
                The leading dimension of the vector X. LDX >= 0.
