I am not currently working on it, but if you need any help or a bug fix I will do my best to get to it. I would recommend the compiled FEAST code for anything serious. Unfortunately there are not any Julia bindings for it (as far as I know), I tried to make one a few years ago but had trouble with the binary packaging toolchain for Julia.
Current state of the library:
threading / parallel processing doesn't work quite right
some FEAST variants not implemented or not working
if I ever revisit my thesis work, I will probably rewrite the codebase entirely to work for a slightly broader class of contour based algorithms
the nonlinear solvers should work but the implementations aren't particularly robust, and convergence properties of the iteration are not well understood
