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.
Algebraic manipulation and repeated use of Gaussian integration.
Care must be taken to choose the integration cut-off properly.
Same as for the low memory version (10.2 seconds). However if many integrals are to be calculated, the required time for each additional integral is only 1.5 seconds.
