DLASCL2 performs diagonal scaling on a vector.

Function/Subroutine Documentation

subroutine dlascl2 (integer M, integer N, double precision, dimension( * ) D, double precision, dimension( ldx, * ) X, integer LDX)

DLASCL2 performs diagonal scaling on a vector.  

Purpose:

 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.
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, 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 >= M.
