create a 3x3 matrix calculator in matlab

To create a 3x3 matrix calculator in MATLAB, you can follow these steps:

1. Define the 3x3 matrices: A, B, and the result matrix (C).
2. Prompt the user to enter values for the elements of matrices A and B.
3. Perform the desired operation on the matrices (e.g. addition, subtraction, multiplication).
4. Store the result in matrix C.
5. Display the result to the user.

Here's an example implementation that performs matrix addition:

main.m
% Step 1: Define the matrices
A = zeros(3, 3);
B = zeros(3, 3);
C = zeros(3, 3);

% Step 2: Prompt the user for input
disp("Enter elements of matrix A:")
for i = 1:3
    for j = 1:3
        A(i, j) = input(sprintf("A(%d, %d): ", i, j));
    end
end

disp("Enter elements of matrix B:")
for i = 1:3
    for j = 1:3
        B(i, j) = input(sprintf("B(%d, %d): ", i, j));
    end
end

% Step 3: Perform matrix addition
C = A + B;

% Step 5: Display the result
disp("Result:")
disp(C);

You can modify this code to perform different operations like subtraction or multiplication by changing the respective operators in Step 3 (e.g. C = A - B; for subtraction).
