MATLAB: MATLAB has a confusing function name such as griddata (or griddatan)

Question

I am really confused by the function names griddata and griddatan, because these function names are prefixed by grid whereas the functions are actually doing scattered data interpolation, rather than gridded data interpolation.

In contrast, interpolant class names such as griddedInterpolant (gridded data interpolation) and scatteredInterpolant (scattered data interpolation) have no confusion at all, because these names are consistent with their functional behaviors.

Answer 1

griddata is a verb and noun. It puts the data into a grid, which is the verb "grid"

griddedInterpolant is an adjective and a noun.
