Can Functions Have a Built-In Self-Test?

Hi All

I'm trying to deterimine if there is a self-testing call or something for Matlab functions, similar to Octave's Self-Test Mode? It would be very helpful to be able to embed the tests into the function itself.

You can do something like this

function y = addStuff(x)
% adds everything in input 'x' (numeric)
% if 'x' is a string that equals 'test', it runs a self-test.
if ischar(x) && isequal('test',lower(x))
    addStuff(1:99); % your test inputs
    return
end
y = sum(x(:)); 
end
