                    if DICO = 'C', JOBE = 'I' and JOBD = 'F'.
          The formulas for other cases, e.g., for JOBE &lt;&gt; 'I' or
          CKPROP = 'C', contain additional and/or other terms.
          The minimum value of LDWORK for all cases can be obtained
          in DWORK(1) when LDWORK is set to 0 on entry.
          For good performance, LDWORK must generally be larger.

          If LDWORK = -1, then a workspace query is as
