numpy.polynomial.polynomial.polydiv — NumPy v2.2 Manual (original) (raw)

polynomial.polynomial.polydiv(c1, c2)[source]#

Divide one polynomial by another.

Returns the quotient-with-remainder of two polynomials c1 / c2. The arguments are sequences of coefficients, from lowest order term to highest, e.g., [1,2,3] represents 1 + 2*x + 3*x**2.

Parameters:

c1, c2array_like

1-D arrays of polynomial coefficients ordered from low to high.

Returns:

[quo, rem]ndarrays

Of coefficient series representing the quotient and remainder.

Examples

from numpy.polynomial import polynomial as P c1 = (1, 2, 3) c2 = (3, 2, 1) P.polydiv(c1, c2) (array([3.]), array([-8., -4.])) P.polydiv(c2, c1) (array([ 0.33333333]), array([ 2.66666667, 1.33333333])) # may vary
