:fortran_help: "      SUBROUTINE DLARSCL2 ( M, N, D, X, LDX )\n\n\
  *  Purpose\n\
  *  =======\n\
  *\n\
  *  DLARSCL2 performs a reciprocal diagonal scaling on an vector:\n\
  *    x <-- inv(D) * x\n\
  *  where the diagonal matrix D is stored as a vector.\n\
  *\n\
  *  Eventually to be replaced by BLAS_dge_diag_scale in the new BLAS\n\
  *  standard.\n\
  *\n\n\
  *  Arguments\n\
  *  =========\n\
  *\n\
  *     M       (input) INTEGER\n\
  *     The number of rows of D and X. M >= 0.\n\
  *\n\
  *     N       (input) INTEGER\n\
  *     The number of columns of D and X. N >= 0.\n\
  *\n\
  *     D       (input) DOUBLE PRECISION array, dimension (M)\n\
  *     Diagonal matrix D, stored as a vector of length M.\n\
  *\n\
  *     X       (input/output) DOUBLE PRECISION array, dimension (LDX,N)\n\
  *     On entry, the vector X to be scaled by D.\n\
  *     On exit, the scaled vector.\n\
  *\n\
  *     LDX     (input) INTEGER\n\
  *     The leading dimension of the vector X. LDX >= 0.\n\
