Nature of problem:
Problems in physics, chemistry, applied mathematics as well as in other fields, are often in need of an efficient 3-D convolution quadrature.

Solution method:
Algebraic manipulation and repeated use of Gaussian integration.

Restrictions:
Care must be taken to choose the integration cut-off properly.

Running time:
Depending on the order of the polynomials chosen. The provided test run took 10.2 cpu seconds on the CD4680.
