R scripts to explain the algorithms of simplex projection and S-map. In the scripts, simplex projection (Sugihara & May 1990) and S-map (Sugihara 1994) are implemented without using existing EDM ...

"TDA typically aims at extracting topological signatures from a point cloud in $\\mathbb R^d$ or in a general metric space. By studying the topological of the point clouds, we actually mean studying ...
