interpax
interpax is a library for interpolation and function approximation using JAX.
Includes methods for nearest neighbor, linear, and several cubic interpolation schemes in 1d, 2d, and 3d, as well as Fourier interpolation for periodic functions in 1d and 2d.
Coming soon: - Spline interpolation for rectilinear grids in N-dimensions - RBF interpolation for unstructured data in N-dimensions - Smoothing splines for noisy data
Installation
interpax is installable with pip:
pip install interpaxUsage
import jax.numpy as jnp
import numpy as np
from interpax import interp1d
xp = jnp.linspace(0, 2 * np.pi, 100)
xq = jnp.linspace(0, 2 * np.pi, 10000)
f = lambda x: jnp.sin(x)
fp = f(xp)
fq = interp1d(xq, xp, fp, method="cubic")
np.testing.assert_allclose(fq, f(xq), rtol=1e-6, atol=1e-5)For full details of various options see the API documentation
