/*  Purpose */
/*  ======= */

/*  ZLARSCL2 performs a reciprocal diagonal scaling on an vector: */
/*    x <-- inv(D) * x */
/*  where the DOUBLE PRECISION diagonal matrix D is stored as a vector. */

/*  Eventually to be replaced by BLAS_zge_diag_scale in the new BLAS */
/*  standard. */

/*  Arguments */
/*  ========= */

/*     M       (input) INTEGER */
/*     The number of rows of D and X. M >= 0. */

/*     N       (input) INTEGER */
/*     The number of columns of D and X. N >= 0. */

/*     D       (input) DOUBLE PRECISION array, length M */
/*     Diagonal matrix D, stored as a vector of length M. */

/*     X       (input/output) COMPLEX*16 array, dimension (LDX,N) */
/*     On entry, the vector X to be scaled by D. */
/*     On exit, the scaled vector. */

/*     LDX     (input) INTEGER */
/*     The leading dimension of the vector X. LDX >= 0. */
