Some inventions operate in a recursive or iterative manner. This could be so of a machine that repeats actions or functions on a single article or to produce multiple articles, or operates on data ...

This Java recursion tutorial shows you how to create a recursive Java factorial function and compares these methods to iterative ones.

I have written a function to calculate the Runge-Kutta numerical approximation of the differential equation dy/dt = -2ty^2 w/ initial conditions y(0)=1 from t=0 to t=10. The function worked when I ...

Recursion has more expressive power than iterative looping constructs. I say this because a while loop is equivalent to a tail recursive function and recursive functions need not be tail recursive.
