Ran in:
Assuming that p and q are real numbers, do you understand there will ALWAYS be three solutions to the problem, and that for many values of p and q, exactly two of those solutions will be complex valued?
cubicroots = @(p,q) roots([1 0 p q]);
format long
cubicroots(2,3)
ans =
0.500000000000000 + 1.658312395177701i 0.500000000000000 - 1.658312395177701i -1.000000000000000 + 0.000000000000000i
