DLASCL2 performs a diagonal scaling on a vector:


   x <-- 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.

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, length 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.
