find the p value in matlab

In order to find the p-value in Matlab, you can perform a hypothesis test using the pvalue() function from the Statistics and Machine Learning Toolbox. Here is an example:

main.m
% Generate some sample data
x = randn(100,1);
y = randn(100,1);

% Perform two-sample t-test
[h,p] = ttest2(x,y)

% The p-value is stored in variable p

In this example, we have two samples of data (x and y) and we want to test if they have the same mean. The ttest2() function performs a two-sample t-test and returns a logical variable h indicating if the null hypothesis should be rejected, and the p-value in variable p. You can access the p-value by simply printing the value of p.
