Matlab: factorials without for loops or colon

[koryargonic]

The Problem: Write a function that finds the factorial of a positive integer without using for or while loops, the factorial function, or the : range operator.

Honestly, I don't really know how to start with this one. If I were able to use a for loop it would be easy, and I don't see how I can do this with conditionals. Any ideas/hints?

Think recursion.
