polyadd
(a1, a2)[source]¶ Find the sum of two polynomials.
LAX-backend implementation of
polyadd()
. Original docstring below.Returns the polynomial resulting from the sum of two input polynomials. Each input must be either a poly1d object or a 1D sequence of polynomial coefficients, from highest to lowest degree.
- Parameters
a2 (a1,) – Input polynomials.
- Returns
out – The sum of the inputs. If either input is a poly1d object, then the output is also a poly1d object. Otherwise, it is a 1D array of polynomial coefficients from highest to lowest degree.
- Return type
ndarray or poly1d object

Examples
>>> np.polyadd([1, 2], [9, 5, 4]) array([9, 6, 6])
Using poly1d objects:
>>> p1 = np.poly1d([1, 2]) >>> p2 = np.poly1d([9, 5, 4]) >>> print(p1) 1 x + 2 >>> print(p2) 2 9 x + 5 x + 4 >>> print(np.polyadd(p1, p2)) 2 9 x + 6 x + 6
