MATLAB: Is it possible to write a function with two different kind of output modes

Question

How to write a function which can be used as y1 = myfunc(), or [y2,z] = myfunc(), but y1 will not be equal to y2!

Answer 1

Use nargout, something like this:

function [X,Y] = myfun()
if nargout==2
    X = 1;
    Y = 2;
else
    X = 0;
end
end
