This release adds support for sparse matrices. Specifically, sparse matrices stored in compressed-sparse-row (CSR) form. As part of the release, the following additions were made.
- Overloading matmul to accommodate sparse matrix multiplication
- Overloading size to query the dimensional information of a sparse matrix
- Overloading transpose to transpose a sparse matrix
- Overloading operators to support interaction with sparse matrices
- Addition of an LU factorization and solver routine for sparse matrices
- Addition of a preconditioned GMRES solver for sparse matrices
- Conversion routines for dense, diagonal, and banded matrices to sparse format
- Conversion routines from sparse format to dense format
- Overload assignment operator to perform conversions between sparse to dense and dense to sparse formats in a comfortable manner
