Banded Tridiagonal Matrices in PETSc

[Tim Stitt]

Hi,

I was just wondering if PETSc has any special provision for banded 
tridiagonal complex matrices when used in conjunction with KSPSolve(). 
Are there any special PETSc matrix types or factorisation/solver methods 
that benefit more from this matrix form?

Currently I am just using standard AIJ representation in my 
serial/parallel codes.

I would be grateful for any thoughts.

Thanks,

Tim.
