Why do my functions suddenly return values in ASCII code?
显示 更早的评论
I have made simple functions in MatLab. For example:
function add(a,b)
fprintf('%d + %d = %d\n',a,b,a+b);
end
This used to work. However, using MatLab again after a while, this same function now returns values in ASCII code. Basically, given the inputs "4" and "5",
Before:
4 + 5 = 9
Now:
52 + 53 = 105
I don't remember doing anything that would cause this change. Simply typing "4 + 5" in the command window returns 9, but the problem arises when I make functions. Advice would be appreciated. (Version: R2022a)

What exactly you are expecting? The code works according to the way it is written.

"but the problem arises when I make functions."
The problem arises when you call functions:
Solution: use function syntax.

"but I just want to fix the formatting if that makes sense."
Changing the formatting cannot "fix" the fact that you call the function with incorrect inputs.

You accidentally used "command function equivalence". When you name a function without using () then the arguments you input are passed to the function as character vectors.
add 4 5
add(4, 5)
function add(a,b)
fprintf('%d + %d = %d\n',a,b,a+b);
end

This also commonly happens in a standalone application. See the "Using a MATLAB File You Plan to Deploy" section on this documentation page.
