numpy.polynomial.polynomial.polydiv — NumPy v1.11 Manual (original) (raw)
numpy.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, c2 : array_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]))
