numpy.polynomial.polynomial.
polymul
Multiply one polynomial by another.
Returns the product of two polynomials c1 * c2. The arguments are sequences of coefficients, from lowest order term to highest, e.g., [1,2,3] represents the polynomial 1 + 2*x + 3*x**2.
1 + 2*x + 3*x**2.
1-D arrays of coefficients representing a polynomial, relative to the “standard” basis, and ordered from lowest order term to highest.
Of the coefficients of their product.
