**networkx** gives adjacency matrices as sparse matrices and that is necessary, since for larger graphs with >100000 nodes with sparse connections, we can have a sparse e.g. coo matrix but a dense mat…

**Concisely describe the proposed feature**
I'm considering adding new functions to ti.Matrix, such as PCA, Cholesky decomposition, Strassen algorithm for ``__matmul__``, etc.

The following matrix types can be express used to build interval matrix that are only affected by some parameters (ie. parametric interval matrices):
- `(A0, A1, p)` --> `A0 + p A1` --
