Factorials are used for many different applications, such as Taylor series, combinatorial probability, permutations and modelling rate of growth. The factorial of a positive integer n is defined as:

Alternatively, the factorial of n can be written recursively as

(a) Write a function that calculates the factorial using a loop:
function f = MyFactorial(x)
(b) Write an mfile that prompts the user to enter a number and uses the function in part (a) to calculate the factorial.

A good problem for anyone starting out with any programming language. Where are you having problems and what have you got so far.
