create a random square matrix a whose size is n n store in a variable ind all the integers from 1 to m in matlab

To create a random square matrix a of size n x n in MATLAB, where n is a variable, you can use the randi function to generate random integers and reshape the array into a square matrix. To store all the integers from 1 to m in a variable, you can use the 1:m notation.

Here's an example code snippet in MATLAB:

main.m
n = 5;      % size of the square matrix
m = n^2;    % total number of integers

% Generate random integers from 1 to m
integers = 1:m;

% Create a random square matrix of size n x n
a = reshape(randi(m, 1, n^2), n, n);

In this example, n is set to 5 to create a 5x5 square matrix. The total number of integers, m, is calculated by squaring n. The randi function generates random integers from 1 to m, and the reshape function is used to reshape the array into a square matrix by specifying the dimensions as n x n.

Finally, the variable a will contain the randomly generated square matrix, and the variable integers will contain all the integers from 1 to m.
