Binomal theorem

This m-file gives the expansion of powers of sums of any real or complex numbers x and y, and any nonnegative integer n. It is also known as the Newton's binomial. From it emerges the discrete binomial (positive) distribution.

Syntax: function bintheor(x,y,n)

Input:
x,y - pair of interested terms to expand
n - coefficient/power to increase the binomial theorem

Output:
- result of the Binomial theorem sum (default)
- vector of the binomial theorem values (optional)
