A polynomial is defined by the coefficients array, which can be real or complex numbers. The first coefficient belongs to the highest degree term; the last one is the constant term. The number of coefficients automatically defines the polynomial degree. If your polynomial misses a term, just set zero as its coefficient. Both polynomial coefficient and sample variable value can be either real or complex. (For real number, enter zero in the imaginary part.)
