NAME
       dlarscl2.f -

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

Function/Subroutine Documentation
   subroutine dlarscl2 (integerM, integerN, double precision, dimension( * )D, double precision, dimension( ldx, * )X, integerLDX)
       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 D and 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.
