I've recently made a lot of research and extracurricular code available at my GitHub location (https://github.com/bradleypmartin). Some of it is currently in more of a "data dump" format, so look forward to my branching and cleaning up a lot of it over the next days and weeks! There are some Matlab and C++ examples in there now, with basic Python notebooks to follow. Topics explored in these collections include my Ph.D. and post-Ph.D. research into numerical solution of PDEs, coursework in general inverse and multigrid methods, and exploratory work in data science. Enjoy!
