What command are you using to call ADDE?
What is the output of the following commands?
which zeros -all
which size

Answering the questions in my comment above will clarify things, but I expect you are calling ADDE with either no arguments or one argument. For example
ADDE(1,2)
works, but
ADDE(1)
gives the error you see.
function [y1] = ADDE(t,y)
y1 = zeros(size(y));
end

That is also the error you would get if you tried to call this function using the "Run" button in the edit window (and it will also pop up a window explaining why).

When you press the green Run button to run your code, then MATLAB does not go looking in the base workspace for definitions of the input parameters.
When you have named input parameters to a function, then inside the function itself, MATLAB will never search for values for the parameters. There are some circumstances under which MATLAB will search for variables, but those circumstances never apply to named parameters of the function.

Hi Thobias,
"Not enough input arguments" typically is thrown when the function is called without the required input variables; i.e.
[y1] = ADDE()
rather than;
t = 1:100;
y = 100;
[y1] = ADDE(t,y) % The important thing here is that t and y are defined and then included in your function call
