Perhaps the name of the function needs to be changed?

Agreed. The Test Suite is failing because it is (now) calling the built-in MATLAB function roots(p). https://mathworks.com/help/matlab/ref/roots.html

I don't think this problem will pass anytime as the test suite is faulty. In assertion your_function(x) is used and when i test my code Undefined function or variable 'x' occurs.
