Re: Numerical Differentiation and Integration of Array Data

I worked out a version of the central difference algorithm in c, although I'm
having a rather comical result with it.

When ever I increase the number of data points by a factor of ten, the
integrated results decreased by a factor of ten.

I could post the code if you like.  I was thinking I had done something
slick, although the data points thing is just buggering me.

I had looked at using diff, although I had trouble working out how to change
it from backward looking to forward looking.  The example I found was
confusing.
