Functions | |
real function | sla_porcond (uplo, n, a, lda, af, ldaf, cmode, c, info, work, iwork) |
SLA_PORCOND estimates the Skeel condition number for a symmetric positive-definite matrix. | |
subroutine | sla_porfsx_extended (prec_type, uplo, n, nrhs, a, lda, af, ldaf, colequ, c, b, ldb, y, ldy, berr_out, n_norms, err_bnds_norm, err_bnds_comp, res, ayb, dy, y_tail, rcond, ithresh, rthresh, dz_ub, ignore_cwise, info) |
SLA_PORFSX_EXTENDED improves the computed solution to a system of linear equations for symmetric or Hermitian positive-definite matrices by performing extra-precise iterative refinement and provides error bounds and backward error estimates for the solution. | |
