how to code a binomial distribution? in matlab

The binomial distribution is used to model the number of successes out of a fixed number of trials, with each trial having the same probability of success. Here is an example code in MATLAB to generate and plot the binomial distribution of 10 trials with success probability of 0.5:

main.m
% Define parameters
n = 10; % number of trials
p = 0.5; % probability of success

% Generate binomial distribution
x = 0:n; % possible number of successes
y = binopdf(x, n, p); % probability mass function

% Plot binomial distribution
stem(x, y);
title('Binomial Distribution');
xlabel('Number of Successes');
ylabel('Probability');
grid on;

In this code, we first define the parameters n and p. We then use the binopdf function to generate the probability mass function of the binomial distribution for possible number of successes x between 0 and n. Finally, we use the stem function to plot the distribution.

Note that in the stem function, we use x as the X-axis and y as the Y-axis, as we want to plot the probability of each possible number of successes. We also add labels and a title to the plot, as well as turning on the grid for easier visualization.
