Please fix the test suite.

The arguments need to be supplied to the function, as in:
assert(isequal(your_fcn_name(b, n),y_correct))

There is still a problem with the test suite. The quantity ff is not defined in test suite problems 2 and 3.

Also, note that the input n (polynomial order) refers to the highest-powered term in the series, NOT the number of series terms.
