Numerical Integration
Integrate a nonlinear function of one variable using Quadpack.
When called with two arguments, this function allows you set options
parameters for the function `quad'.

Compute derivative and integral weight matrices for orthogonal
collocation using the subroutines given in J.
Numerically evaluate a double integral.
Numerically evaluate a triple integral.
