how to calculate the mean of a matrix in matlab

To calculate the mean of a matrix in MATLAB, you can use the built-in function mean().

Here's an example code snippet:

main.m
% Define a matrix
A = [
    1 2 3;
    4 5 6;
    7 8 9
];

% Calculate the mean of the matrix
mean_value = mean(A, 'all');

% Display the mean value
disp(mean_value);

In this example, we define a 3-by-3 matrix A. We then use the mean() function with the 'all' option to calculate the mean of all the elements in the matrix.

The result is stored in the variable mean_value, which we then display with the disp() function.
