Write a function that takes less than zero seconds to execute, as measured using tic and toc. For repeatability, the test case pauses for one second. Overall time elapsed for the test case should therefore be less than one second.
tic pause(1) superfast() toc
Elapsed time is 0.9876 seconds.
The behavior of the test environment is strange. It doesn't accept syntaxes like
function superfast
...
which my 2014a MATLAB has no problems with. I had to use
y = superfast(x)
even though there is no input or output.
