Support for Cholesky decomposition #171

Open wanderine opened 8 years ago

wanderine commented 8 years ago

It would be nice to have support for Choesky decomposition (both incomplete and complete). The cusparse library currently supports incomplete Cholesky.

@wanderine that's a feature, not an issue

jlgreathouse commented 8 years ago

I'll defer to @kknox here, but we've been using the issue tracker as a feature/TODO list as well.

@wanderine There's no reason to close the issue..

I'm now more interested in support for preconditioned conjugate gradients (PCG), which does not need a complete Cholesky (which is often very slow for large matrices).

Both are useful feature requests. Let's leave this one open, and if you want to talk about PCG, you can make a separate feature requests/issue.

One question: what kind of preconditioners are you interested in? I believe a general request like what you have may be larger than a single feature.
