10
11           IMPLICIT        NONE

13           INTEGER         M, N, LDX
14
15           COMPLEX*16      X( LDX, * )

PURPOSE

20       ZLARSCL2 performs a reciprocal diagonal scaling on an vector:
21         x <-- inv(D) * x
22       where the diagonal matrix D is stored as a vector.
23       Eventually  to be replaced by BLAS_sge_diag_scale in the new BLAS stan‐
24       dard.
25

ARGUMENTS

27       The size of the vectors X and D.
28
29       D      (input) DOUBLE PRECISION array, length N
30              Diagonal  matrix  D,  stored  as  a  vector  of  length  N.    X
31              (input/output) COMPLEX*16 array, length N On entry, the vector X
32              to be scaled by D.  On exit, the scaled vector.
