`numpy.polynomial.polynomial:polymul`

source: /numpy/polynomial/polynomial.py :330

Signature

def polymul ( c1 , c2 )

Summary

Multiply one polynomial by another.

Extended Summary

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.

Parameters

c1, c2 : array_like: 1-D arrays of coefficients representing a polynomial, relative to the "standard" basis, and ordered from lowest order term to highest.

Returns

out : ndarray: Of the coefficients of their product.

Examples

from numpy.polynomial import polynomial as P
c1 = (1, 2, 3)
c2 = (3, 2, 1)

✓

P.polymul(c1, c2)
