Can you give me a link to a paper or a full description of the algorithm used

The ‘cubic’ interpolation method in ‘griddata’function represents the Triangulation-based cubic interpolation and it supports 2-D interpolation only.
Refer to griddata to know more about 2-D or 3-D Scattered Data Interpolation.

Thank you for your answer! Is there perhaps a paper that describes the 'cubic' algorithm in depth? I need it for my batchelors thesis.
