numpy.polynomial.polynomial.polydiv#
- 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
