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.
