Basis
Basis is a concept for orthogonal vectors in GMRES algorithm. Here are the requirements if KS is the object whose type models Basis:- KS[i]: the ith orthogonal vector
- orthogonalize(KS, v, i): the function to perform orthogonalization
- combine(KS, s, x, i): the function to update solution vector x
- Modified Gram-Schmidt the basis for modifed Gram-Schmidt orthogonalization
- Classical Gram-Schmidt the basis for classical Gram-Schmidt orthogonalization with one iterative refinement
