NAME

/home/abuild/rpmbuild/BUILD/lapack-3.12.0/SRC/clascl2.f

SYNOPSIS

Functions/Subroutines


subroutine CLASCL2 (m, n, d, x, ldx)
CLASCL2 performs diagonal scaling on a matrix.

Function/Subroutine 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.
