SLASCL2 performs diagonal scaling on a vector.

Function/Subroutine Documentation

subroutine slascl2 (integerM, integerN, real, dimension( * )D, real, dimension( ldx, * )X, integerLDX)

SLASCL2 performs diagonal scaling on a vector.

Purpose:

SLASCL2 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_sge_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 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 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.
