[CSC 435] Linear Solvers

[Andrew J. Pounds]

So I just went through the linear solver exercise and it is working 
perfectly.  When I was doing the demon in class today I was running with 
-DSPARSE while also doing -DACCURACY_TEST -- those don't go together.

As a side note, the spase matrices I am buiding have a band size of 11 
-- there are 5 upper diagonals and 5 lower diagonals.  Many would not 
consider that sparse.  As such you will most likely find that the 
iterative solvers fail on these.

Now - in truth many partial differential equation solvers will build 
large linear systems with the matrix only having 1 superdiagonal and 1 
subdiagonal.  If you are feeling adventurous and want to see what 
happens in such a case, modify my subroutine that builds the matrices so 
in the sparse case there is only a super and sub diagonal (and a 
diagonal of course).
