There isn't any value, as such, in creating a sparse matrix from a matrix containing no, or very few, zeros.

+1. :-)
@bavani: If you have a question about a certain feature, start with searching for it:
docsearch sparse
If this does not help, search in the internet. If there are still open questions, the forum is a good idea.
