polysub
(a1, a2)[source]¶ Difference (subtraction) of two polynomials.
LAX-backend implementation of
polysub()
. Original docstring below.Given two polynomials a1 and a2, returns
a1 - a2
. a1 and a2 can be either array_like sequences of the polynomials’ coefficients (including coefficients equal to zero), or poly1d objects.- Parameters
a2 (a1,) – Minuend and subtrahend polynomials, respectively.
- Returns
out – Array or poly1d object of the difference polynomial’s coefficients.
- Return type
ndarray or poly1d
Examples
\[(2 x^2 + 10 x - 2) - (3 x^2 + 10 x -4) = (-x^2 + 2)\]>>> np.polysub([2, 10, -2], [3, 10, -4]) array([-1, 0, 2])
