Dear Sirs:
I have a code that must take several inverses from relatively big matrices 
the majority of whose entries are zeroes. It runs hellishly slowly.
 
I am aware that I sholud use sparse array functionalities to make these inverses run faster, but do not know quite how to use them. Can somebody help me?
