NAME
SRC/clascl2.f

SYNOPSIS

  Functions/Subroutines
subroutine clascl2 (m, n, d, x, ldx)
CLASCL2 performs diagonal scaling on a matrix.

Function/Subroutine Documentation

  subroutine clascl2 (integer m, integer n, real, dimension( * ) d, complex, dimension( ldx, * ) x, integer ldx)

CLASCL2 performs diagonal scaling on a matrix.

Purpose:

     CLASCL2 performs a diagonal scaling on a matrix:
       x <-- D * x
     where the diagonal REAL matrix D is stored as a matrix.
     Eventually to be replaced by BLAS_cge_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 COMPLEX 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.
