RBFPREIMG3

RBF pre-image problem by Kwok-Tsang's algorithm.



 Synopsis:
  x = rbfpreimg3(model)
  x = rbfpreimg3(model,nn)

 Description:
  x = rbfpreimg3(model) is an implementation of the algorithm 
    by [Kwok03] to solve the pre-image problem for kernel expansion 
    with RBF kernel. The kernel expansion is given in the input 
    structure model.

  x = rbfpreimg3(model,nn) use to set number of nearest 
    neighbours (default 10).

 Input:
  model [struct] RBF kernel expansion:
   .Alpha [nsv x 1] Weights.
   .sv.X [dim x nsv] Vectors.
   .options.arg [1x1] RBF kernel width.

  nn [1x1] Number of nearest neighbours.
  
 Output:
  x [dim x 1] Pre-image of the RBF kernel expansion.
