Your test suite is not a good one; you shouldn't declare asb to be global. Instead, you should just allow the function declaration to contain 'asb', as in:

function x = asb(x)
x = abs(x)
end

And do you _really_ think we should program MATLAB to try to fix your typos? That's a recipe for disaster!
