make a random 100-by-100 matrix in matlab

main.m
% set the size of the matrix
matrix_size = 100;

% initialize the matrix
random_matrix = zeros(matrix_size);

% loop through the matrix and assign a random number to each element
for row_index = 1:matrix_size
    for col_index = 1:matrix_size
        random_matrix(row_index,col_index) = rand();
    end
