I have a big sparse matrix and it takes lot of time to execute the whole code.

How big is "big sparse matrix"?
How sparse is it -- what percentage of the elements are nonzero?
What are you doing with this sparse matrix?
Are you certain that the sparse matrix indexing is the bottleneck of your code?
With the answers to these questions we have a chance at offering potential improvements to the code.

Sparse matrix always need a lot memory in Matlab, maybe you can try Visual C++.
