how to make my own sparse matrices function that works just like "sparse" matlab bulid-in function

how to make my own sparse matrices function that works just like "sparse" Matlab build-in function? Thanks

[Steven Lord]

Why not just use the built-in sparse function and data type?

[James Tursa]

Well, pick a sparse format and start coding, I guess. There are plenty of online algorithms you can code up for the functions it will support. This will be a HUGE amount of work, of course ...

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.
