IML++
IML++, or the Iterative Methods Library, is a C++ library for solving linear systems of equations. It is said to be "templated" in the sense that the same source code works for dense, sparse, and distributed matrices.
Some of the supported solutions methods are:
- Richardson Iteration
- Chebyshev Iteration
- Conjugate Gradient (CG)
- Conjugate Gradient Squared (CGS)
- BiConjugate Gradient (BiCG)
- BiConjugate Gradient Stabilized (BiCGSTAB)
- Generalized Minimum Residual (GMRES)
- Quasi-Minimal Residual Without Lookahead (QMR)
