How can I quickly obtain the inverse of a square sparse matrix?

Dear All,
I have a square sparse matrix A. I use the following way to obtain its inverse:
invA = A \ eye(size(A));
I am wondering if there is a faster way to obtain invA.
Thanks a lot.
Benson

potentially, if you have more information about the properties of A, you can specify them in a call to linsolve
