hello there!

i was wondering if someone could point me to a paper on how to implement banded matricies in java (or any other language for that matter, preferably not too syntatically different).

i will use the banded matrix to store adjacency data for a graph for a 3rd year joint comp. science and maths degree. the nodes in the graph are likely to be "locally" connected (i.e. clusters).

at the moment i am using a triangular-come-symmetric matrix, however this is not the most efficient.

thanks,
tian
