(2002). Modeling the excitability of mammalian nerve fibers: Influence of after potentials on the recovery cycle. J. Neurophysiol., 87, 995–1006.\n\nIt was then reimplemented in MATLAB, published at:\n\nhttps://code.google.com/p/mrg-matlab/\n\nThis is a reimplementation of the MATLAB code (also found in ./reference/) in C++.\n","project_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmm318%2Fmrg-cpp","html_url":"https://awesome.ecosyste.ms/projects/github.com%2Fmm318%2Fmrg-cpp","lists_url":"https://awesome.ecosyste.ms/api/v1/projects/github.com%2Fmm318%2Fmrg-cpp/lists"}
