This bug is still present in Octave 4.2.0.

The function griddata.m claims to support the method "cubic" in its help text, but trying to use it results in an error message: "error: griddata: cubic interpolation not yet implemented".

A simple script to reproduce this:

Out of curiosity, with the possible intention of implementing this feature, what type of cubic mapping is used? Splines? If I am told what type we should use, I will try to implement this version of the function.

Using the 3.4.3 binary distribution for Windows, I receive the error:

griddata: cubic interpolation not yet implemented

when using the following:

griddata(x,y,z,xx,yy, "cubic");

According to the documentation, "cubic" is a valid parameter.
