Details:

Hello,

I introduced the following typo in a function code:
if (length(varargin) > 1)
  some_par = varargin(1);
  varargin =  varagin(2:end) % <= notice the typo
else
  some_par = ones(size(x));
endif

This generate the following error message:
"invalid use of end" 

The problem is that there is obviously no varagin variable. Could the error
clearly point to the fact that the variable associated with the 'end' keyword
does not exist, and not about the use of end itself?

Regards

Pascal
