I read the link and also changed all_va_args with varargin and  found an error 
on the fpica call arguments. The program still not recognize the following 
commands: switch with == applied to a number and the pplottype argument which 
is defined as 'classic' (see Octave 16> above). When I run the program without 
graphics the task ends normally. I suppose there are still some problem with 
the code.
