components, a Python code which organizes contiguous cells into labeled clusters, for a 1D, 2D, or 3D array. This code has uses in image analysis and percolation simulation.

components is available in a C version and a C++ version and a FORTRAN90 version and a MATLAB version and a Python version.
percolation_simulation, a Python code which simulates a percolation system. A rectangular region is decomposed into a grid of MxN squares. Each square may be porous or solid. We are interested in a path of porous squares connecting the top and bottom, or the left and right boundaries. The original MATLAB code was written by Ian Cooper.
