RBF interpolation

Hello,

    I want to implement RBF interpolation in Matlab for 2D signal (image) 
interpolation. What I like to know is:



1- Is there any freely available RBF interpolator source code for Matlab?

2- How can I implement it? I read a lot about its theory but I couldn't 
figure out how an implementation is working.

3- If there is a C implementation, I maybe able to port it to Matlab (as a 
MEX file). This is very good as then it is very fast.



Any advice or help is much appreciated.



Best regards

I don=B4t know about freely available RBF interpolator source codes...
nor in matlab nor in C.

But when I=B4ve found myself in your situation I=B4ve found very helpfull
to read the documentation of the toolbox concerning your requirement.

In this case, there is a chapter dedicated to RBFs in the Neural
Network Toolbox. See the section "Radial Basis Networks". The second
sub-section is named "Radial Basis Functions". It begins with the
theoretical aspects, and follows making examples of how to use the
functions that come with the toolbox.

Hope this helps!
