If you are using Mathematica version 6 and your matrix has many zeros, you
should check the commands SparseArray and Band in order to work efficiently
(save computer memory and time).

There are good examples of the use of SparseArray and Band in the
Documentation Center of Mathematica version 6.

In previous Mathematica version SparseArray does exist, but Band does Not
exist.

Hope it helps

Hi.

Anyone here already tried to implement calculus on mathematica using a
500*500 dimension matrix?

Do you know if it works?

Thank you!
