CLARSCL2(1) | LAPACK routine (version 3.2) | CLARSCL2(1) |
NAME¶
CLARSCL2 - performs a reciprocal diagonal scaling on an vector
SYNOPSIS¶
- SUBROUTINE CLARSCL2
- ( M, N, D, X, LDX )
IMPLICIT NONE INTEGER M, N, LDX COMPLEX X( LDX, * ) REAL D( * )
PURPOSE¶
CLARSCL2 performs a reciprocal diagonal scaling on an vector:
x <-- inv(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.
ARGUMENTS¶
The size of the vectors X and D.
- D (input) REAL array, length N
- Diagonal matrix D, stored as a vector of length N. X (input/output) COMPLEX array, length N On entry, the vector X to be scaled by D. On exit, the scaled vector.
