interpax_fft

interpax_fft is a library for Fourier interpolation and function approximation using JAX.

interpax_fft extends interpax with more utilities for (pseudo-spectral) interpolation.

Installation

interpax_fft is installable with pip:

pip install interpax_fft

For full details of various options see the API documentation.
