Do you want to interpolation on regular grid (i.e. same space along one axis, but each axis can have different space)? It seems that interp2d of https://github.com/adam-coogan/jaxinterp2d accepts x and y with different sizes, but CartesianGrid doesn't. Okay I …

JAX provides a number of interfaces to compute convolutions across data, including: For basic convolution operations, the jax.numpy and jax.scipy operations are usually sufficient. If you...

Now let's define a 2D Gaussian using jax.numpy. You can construct function just like numpy with a few small caveats. R = jnp.array([[jnp.cos(theta), -jnp.sin(theta)], [jnp.sin(theta),...
