jax.numpy.polysub#
- jax.numpy.polysub(a1, a2)[source]#
Difference (subtraction) of two polynomials.
LAX-backend implementation of
numpy.polysub()
.Original docstring below.
Note
This forms part of the old polynomial API. Since version 1.4, the new polynomial API defined in numpy.polynomial is preferred. A summary of the differences can be found in the transition guide.
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:
a1 (array_like or poly1d) – Minuend and subtrahend polynomials, respectively.
a2 (array_like or poly1d) – Minuend and subtrahend polynomials, respectively.
- Returns:
out – Array or poly1d object of the difference polynomial’s coefficients.
- Return type:
ndarray or poly1d
