I would like to experiment and check the different matrix behavior.Thanks

Creating your own function to create a sparsely stored matrix from a non-sparse one is not difficult at all, but writing all the code that would support your created structure for all the operations you might want to do, as Matlab's builtin sparse data-type supports would be a nightmare

As James said this will be a LOT of work. There is a paper from 1991 describing the design and implementation of sparse matrices in the PDF documentation that may interest you.
