i have a nm matrix calculated using m-code. i need to rerun the code for incremented input values, obtain new nm matrix. get difference between both matrices in matlab

To create an n x m matrix in MATLAB using m-code, you can use the zeros function followed by assigning values to individual elements. Here's an example:


main.m
% Initialize matrix with zeros
n = 3;
m = 4;
matrix = zeros(n, m);

% Assign values to individual elements
matrix(1, 1) = 2;
matrix(2, 3) = 5;
matrix(3, 2) = 8;

disp(matrix);

To rerun the code for incremented input values and obtain a new n x m matrix, you can put the code inside a loop and change the input values in each iteration. Here's an example using a for loop:


main.m
n = 3;
m = 4;

for i = 1:3
    % Calculate new input values based on iteration index i
    input_value = i * 2;
    
    % Initialize matrix with zeros
    matrix = zeros(n, m);

    % Assign values to individual elements
    matrix(1, 1) = input_value;
    matrix(2, 3) = input_value + 3;
    matrix(3, 2) = input_value + 6;

    disp(matrix);

To get the difference between two matrices in MATLAB, you can use the - operator. Here's an example:


main.m
n = 3;
m = 4;

% Initialize matrix1
matrix1 = zeros(n, m);
matrix1(1, 2) = 2;
matrix1(3, 4) = 5;

% Initialize matrix2
matrix2 = zeros(n, m);
matrix2(1, 2) = 3;
matrix2(2, 3) = 7;

% Calculate difference between matrix1 and matrix2
diff_matrix = matrix1 - matrix2;

disp(diff_matrix);
