The use of starred expressions to create data detracts from understanding required data structure

>>> data = f(*np.meshgrid(x, y, z, indexing='ij', sparse=True))

Starred expressions can't be readily examined. For users who are attempting to familiarize themselves with the required data structures for RegularGridInterpolator, it adds unnecessary additional complexity.

I would suggest creating the meshgrid outside of the function call so that the purpose of the starred expression is more easily understood.

Despite the description of the structure of data below, it is difficult to adapt to unique user use cases.

Great - I will start taking a look.
