hypercube_integrals, a FORTRAN77 code which returns the exact value of the integral of any monomial over the interior of the unit hypercube in M dimensions.
The interior of the unit hypercube in M dimensions is defined by
0 <= X(1:M) <= 1.
The integrands are all of the form
F(X) = product ( 1 <= I <= M ) X(I)^E(I)
where the exponents are nonnegative integers.
