I have reviewed your code and have a few observations:
- In the code segment below, consider a scenario where the old value is 2, and the roll value is 1 (the minimum possible). When you add the roll value to the old value, the result is 3, which will always be greater than the old value.
- Consequently, the `if` block is always executed, causing the color to change to green regardless.
roll = randi([1, 6]); % 1
oldValue = matrix(rowToChange, colToChange); % 2
matrix(rowToChange, colToChange) = matrix(rowToChange, colToChange) + roll; % 3
if matrix(rowToChange, colToChange) > oldValue
matrix(rowToChange, colToChange) = 5;
end
Please review this logic. Let me know if I can assist you further.
