MATLAB: Function output

Question

Hi!

Have a short question 🙂

I have the following code:

        test = [1 2 3 4];
        test = foo(test);

foo looks like this:

        function [test, out] = foo(test)
             out = 5;

test = foo(test) then return [1 2 3 4] not [1 2 3 4 5] which I thought it would do! What is it I do wrong here?!

One more thing:

If I write like this

        function [test; out] = foo(test)
             out = 5;

A ; instead of , Matlab gives me a syntax error, why?

Thanks!

Answer 1

variant

function out = foo(test)
   out = [test(:)',5];
end

2. You have:

 function [test; out] = foo(test)

but we need to

 function [test, out] = foo(test)
