Matlab help, RBF interpolation

I am trying to solve a question, which asks you to use RBF interpolation (radial basis functions) to smear an image using matlab.

The smear is given by a Gaussian function and is applied along a diagonal line, and use of a Wendland function is also needed to find the original pixel coordinates.

 

Does anyone have any experience in this and would be able to help? I have more info and diagrams I can provide!

I also have a coded example of linear RBF interpolation, but I am stuck on how to apply this to an image and create a smear.

Any ideas would be most appreciated!
