Add specialization of linear algebra functions for example det for symbolic matrices that are sparse

[zvnkk]

Given sparse symbolic matrix determinant does not care about the structure of matrix and does full matrix compuation and it makes impossible to compute determinants of matrices after certain size due to time.
Mathematica implements this feature and computations there are fast.

It's definitely possible. It can be on the menu but it's mostly based on if a contributor gets interested in implementing it.
