function [K,Kt]=CreateMultiLevelKernel(xapp,xtest,kerneloption,level)

% USAGE
%
% [K,Kt]=CreateMultiLevelKernel(xapp,xtest,kerneloption,level)
%
%  This function creates multiscale kernels K and Kt for the <xapp,xapp>
%  and <xtest,xapp>
% 
%  Inputs 
%  xapp and xtest are datasets
%  
%  kerneloption is the wavelet kernel configuration see tensorwavkernel
%  
%  level denotes the decomposition of the kernel. level is a 2 dimension
%  kernel with as many rows as desired decomposition.
%  e.g      level=[-3 0; 1 2; 3 7];
%  decomposes a wavelet kernel from -3 to 7 in 3 kernel with the given
%  level decomposition.
%  if 'vect' is given as a parameters in kerneloption then the
%  decomposition is done according to the vectors given in
%  kerneloption.vect
