- Are these functions expressible by formula or are they tabulated
- data, say from some physical study or experiment. If, as I suspect,
- it the latter then you will have to deal with finding suitable
- approximations (splines, polynomials, rational functions, etc) and
- then aprroximating the integral or derivative. "Numerical Recipes in
- C" by W. Press et al might have material of value to you.

- The above is not a very usefull comment, but it really is a very
- messy area and one has to know the functions well to do a good job.
