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.

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.
