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]))
