CHANGES

  • add SparseMatMul, SparseTensorContract, SparseTensorDot and SparseMatInv for SparseRREF.wl
  • rename the shared library from mathlink/mma_link.cpp to sprreflink/sprreflink.cpp
  • unify API naming rules (e.g. rational_rref to sprref_rat_rref)

- mathlink.* -> sprreflink.*
Functions
- `mod_rref` -> `sprref_mod_rref`
- `rational_rref` -> `sprref_rat_rref`
- `modpmatmul` -> `sprref_mod_matmul`
- `ratmat_inv` -> `sprref_rat_matinv`
