Do Matlab support Kernel formation in Dimensionality reduction?

dimensionality reduction is used in image processing for reducing the size of the images using different algorithms. One of them is using kernels. But I am unable to form Kernels in MATLAB. Any solution?

Is there a very specific algorithm you are looking for? There are several algorithms out there, are you stuck at a specific point in your implementation? please provide code for what you have tried so far.

If not start with File Exchange to see if there are user submitted code that works for:
