MATLAB: Coin toss game simulation.

Question

I'm trying to create a simple coin toss simulation, the game is as follows.

a player flips a coin, if heads they score 1, if tails -1. the player can stop at any point and win the current score divided by the number of games.

I want to create some code that simulates this for say 10 coin tosses and outputs the scores at each toss in for example a vector and the separately outputs the larges score.

any help would be hugely appreciated.

Answer 1

num_toss = 10;
%Toss the coin
vec_toss = rand(num_toss,1) > 0.5;
%Get the average:
mean_vec = cumsum(vec_toss)./(1:num_toss);
