% comparing interest points initialisation
ccmprh=zeros(size(kpl,1)-1,1);
ccmprw=zeros(size(kpl,1)-1,1);
lenkp=length(kp);       % length of kp for 'for loop'
lencmp=length(ccmprh);

So define the variable kpl. You use it in your code. How can MATLAB know what kpl is, if you fail to provide it?

You may consider buying the mind reading toolbox. It is a new set of tools that allow MATLAB to know what you want to do, without your typing anything. It is very expensive though. :)
