While interpolation functions are available builtin in MATLAB, it requires data in specified griddata format. Consider sampling data from an experiment and you are missing some points and you don't want to repeat the experiment but require data at all grid-points for full calculation. This might help.
My data is an AFM image of a butterfly wings and there were missing parts from overlapping regions. Thanks to my colleague Nandula for the data.
