**roulette_simulation**,
a MATLAB code which
simulates the spinning of a roulette wheel and the evaluation of
certain common roulette bets.

A fair wheel would have 36 pockets; a European wheel has an extra "0" pocket, while a Las Vegas wheel has "0" and "00" pockets. Pockets "0" and "00" are in general losers for the player. Players can bet on a single number, red or black, odd or even, low or high, column 1, 2 or 3, or more complicated bets. The payoffs are computed as though there were no 0 pockets, so this gives the house a considerable edge.
