create simple program that can add and subtract two matrices in matlab

To create a simple program in MATLAB that can add and subtract two matrices, you can follow the steps below:

Step 1: Define the matrices with their values. The matrices should have the same dimensions for addition and subtraction to be possible.

main.m
matrix1 = [1 2 3; 4 5 6; 7 8 9];
matrix2 = [9 8 7; 6 5 4; 3 2 1];
66 chars
3 lines

Step 2: Perform addition and subtraction using the + and - operators. If the matrices have different dimensions, MATLAB will throw an error.

main.m
addition_result = matrix1 + matrix2;
subtraction_result = matrix1 - matrix2;
77 chars
3 lines

Step 3: Display the results using the disp function.

main.m
disp("Addition Result:");
disp(addition_result);

disp("Subtraction Result:");
disp(subtraction_result);
105 chars
6 lines

The complete program would look like this:

main.m
matrix1 = [1 2 3; 4 5 6; 7 8 9];
matrix2 = [9 8 7; 6 5 4; 3 2 1];

addition_result = matrix1 + matrix2;
subtraction_result = matrix1 - matrix2;

disp("Addition Result:");
disp(addition_result);

disp("Subtraction Result:");
disp(subtraction_result);
250 chars
12 lines

When you run the program, it will display the addition and subtraction results for the given matrices.
