create simple program that can add and subtract two matrices using if-end statement in matlab

To create a simple program that can add and subtract two matrices using if-end statements in MATLAB, you can follow these steps:

  1. Define the size of the matrices you want to add/subtract.
  2. Initialize two matrices with the given size.
  3. Populate the matrices with values.
  4. Use if-end statements to check if the matrices can be added/subtracted (i.e., they must have the same dimensions).
  5. Perform the addition/subtraction operation.
  6. Display the resulting matrix or store it in a new variable for future use.

Here's an example program that demonstrates this process:

main.m
% Step 1: Define the size of the matrices
rows = 2;
cols = 3;

% Step 2: Initialize two matrices with the given size
matrix1 = zeros(rows, cols);
matrix2 = zeros(rows, cols);

% Step 3: Populate the matrices with values
matrix1 = [1 2 3; 4 5 6];
matrix2 = [7 8 9; 10 11 12];

% Step 4: Check if matrices can be added/subtracted
if size(matrix1) == size(matrix2)
    % Step 5: Perform the addition/subtraction operation
    matrixSum = matrix1 + matrix2;
    matrixDiff = matrix1 - matrix2;
    
    % Step 6: Display the resulting matrix or store it in a variable
    disp("Sum of matrices:");
    disp(matrixSum);
    
    disp("Difference of matrices:");
    disp(matrixDiff);
else
    disp("Matrices cannot be added/subtracted. They must have the same dimensions.");
end

This program will output the sum and difference of the two matrices, provided they have the same dimensions. If the dimensions are different, it will display a message stating that the matrices cannot be added/subtracted.
