Dev #54

Closed Simkern closed 8 months ago

Simkern commented 8 months ago

Krylov basis utilities added to AbstractVector.f90:

mat_mult: Explicit interface for basis-basis multiplication and basis-real matrix multiplication
mat_axpby: Explicit interface for scaled addition of bases and real matrices
mat_zero: Essentially a copy of initialize_krylov_subspace for general usage without reference to Krylov subspaces
mat_copy: Copy basis based on mat_axpby.

Test suites added.
