laplacian_test

laplacian_test, an Octave code which calls laplacian(), which evaluates a discretized approximation to the Laplacian operator on data on an evenly spaced grid, within a circle, an interval, or a torus. For the case of the interval, the data may be supplied on an unevenly spaced grid.
