tetrahedron_monte_carlo


tetrahedron_monte_carlo, a MATLAB code which estimates the integral of a function over a general tetrahedron using the Monte Carlo method.

The library makes it relatively easy to compare different methods of producing sample points in the tetrahedron, and to vary the tetrahedron over which integration is carried out.
