**laplacian_matrix_test**,
a Fortran90 code which
calls laplacian_matrix(), which
carries out computations related to the discrete
Laplacian operator, including full or sparse evaluation,
evaluation for unequally spaced data sampling points,
application to a set of data samples, solution of associated
linear systems, eigenvalues and eigenvectors, and extension
to 2D and 3D geometry.
