Sparse matrices are stored as Compressed Sparse Column and handled mainly by 
functions from
suitesparse [1]. Here is a report about the SparseMatrix class implementation 
in Octave [2].

If you are going to work on PDE solvers have a look at a some of those already 
available before you start coding to avoid duplication [3,4,5].
