Until you post a more specific problem, the only thing I can suggest is to read the documentation available via the Documentation Center. Specifically, the pages that appear with the following entries in the search box SparseArray tutorial/SparseArrays - LinearAlgebra tutorial/SparseArrays - ManipulatingLists The latter two are linked to the page that appears for the first. The links are found near the bottom of the page.
