   I am trying to do a two-dimensional finite difference formulation
   on a CM-200.  For the resulting system of equations Ax=B, I get an
   A maxtrix that looks like this:

    
               |  c    d              e                 |
               |                                        |
               |  b    c    d              e            |
               |                                        |
               |       b    c    d              e       |
               |                                        |
               |           b    c    d               e  |
               |                                        |
               |  a              b    c    d            |
               |                                        |
               |       a              b    c    d       |
               |                                        |
               |            a              b    c    d  |
               |                                        |
               |                 a             b    c   |

   where the space between the centre tridiagonal band and the outer
   bands is two.  Does anyone know of a CMSSL routine that will solve
   such a system?  Or is there anyway to transform this system into
   one that can be solved by another CMSSL sparse system routine?
   The CMSSL routine gen_penta_diag doesn't seem to have a provision
   for spaces between bands.  I would appreciate any suggestions.
