Interpolation on Regular Grids

Interpolation of data defined on regular (possibly unevenly spaced) grids. For an xarray.DataArray, use RegularGridInterpolator, which identifies the axes and selects the interpolator from the number of dimensions; otherwise call the functions below on a pyinterp.Grid built from axes and a numpy array.

Classes
