Detailed Description

Function Documentation

subroutine clascl2 (integer m, integer n, real, dimension( * ) d, complex,dimension( ldx, * ) x, integer ldx)

CLASCL2 performs diagonal scaling on a matrix.

Purpose:

CLASCL2 performs a diagonal scaling on a matrix:
x <-- D * x
where the diagonal REAL matrix D is stored as a matrix.

Eventually to be replaced by BLAS_cge_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 REAL array, length M
Diagonal matrix D, stored as a vector of length M.

X

X is COMPLEX 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.
