NAME
SLARSCL2 - performs a reciprocal diagonal scaling on an vectorSYNOPSIS
- SUBROUTINE SLARSCL2
- ( M, N, D, X, LDX )
- IMPLICIT NONE
- INTEGER M, N, LDX
- REAL D( * ), X( LDX, * )
PURPOSE
SLARSCL2 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
- N (input) INTEGER
- 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) REAL array, length N
- On entry, the vector X to be scaled by D. On exit, the scaled vector.
