fe2d_predator_prey_fast_test, a MATLAB code which calls fe2d_predator_prey_fast(), which applies finite element solvers for predator prey simulations with time and 2D spatial dependence over an arbitrary domain that has been triangulated. A variety of boundary conditions may be specified. The solvers integrate the associated partial differential equations over a given time interval, and create plots of the predator and prey population densities at the final time.

fe2d_predator_prey_fast, matlab programs which implement the finite element method (FEM) for a predator-prey system with time and 2D spatial dependence, in an arbitrary triangulated region, with a variety of boundary conditions, incorporating some Matlab optimizations, by Marcus Garvie.
A number of the test codes use the lake geometry. All such codes will require the list of nodes and elements. Codes which have a mixture of boundary conditions will also require the two files which separate the boundary nodes into those on the outer boundary of the lake, and those which mark the boundary of the island.
