roots -Polynomial roots Syntax r = roots(c) Description r = roots(c) returns a column vector whose elements are the roots of the polynomial c. Row vector c contains the coefficients of a polynomial, ordered in descending powers. If c has n+1 components, the polynomial it represents is . Tips Note the relationship of this function to p = poly(r), which returns a row vector whose elements are the coefficients of the polynomial. For vectors,roots and poly are inverse functions of each other, up to ordering, scaling, and roundoff error.

说明：  AMplitude mod and demodulation
