Reordering the sparse stiffness matrix #20

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Currently no ordering is done on the stiffness matrix to reduce its bandwidth 
or the degree of nodes. But this is known to increase the performance of system 
solvers. The effect of reordering should be investigated.

MATLAB provides symrcm() and colamd() functions for reordering.

colamd() is also available in Tim Davis' SuiteSparse.
