how to solve this issue?. Undefined function 'ge' for input arguments of type 'timeseries'.

Hi, I had had change from Matlab&Simulink release 2018a to a former release 2017a, and my model is now presenting this problem.

Error evaluating 'StopFcn' callback of block_diagram 'PSE_MainModel'. Caused by: Undefined function 'ge' for input arguments of type 'timeseries'.

The stop function does not has any "ge" function, that is something superb strange. This is the script:

if true
  % code
if exist('I','var') && exist('V','var')
 figure(1)
 clf
 n=find(I>=0);
 n=n(end);
 Vglobal=V(1:n);
 Iglobal=I(1:n);

   Pglobal=Vglobal.*Iglobal;
   n=find(Pglobal==max(Pglobal));
   Pmax=Pglobal(n);
   Vmp=Vglobal(n);
   Imp=Iglobal(n);

   subplot(211)
   plot(Vglobal, Iglobal,Vmp,Imp,'or')
   ylabel('Current (A)')
   title(sprintf('Global I-V & P-V characteristics\n %s' ,ModuleName))

   subplot(212)
   plot(Vglobal, Pglobal,Vmp,Pmax,'or')
   ylabel('Power (W)')
   xlabel('Voltage (V)')
end
end

Could you help me with this?. This script is part of a Simpowersystem model, it is used to portraying the graphs of power in it.

n=find(I>=0);

The formal name of the >= operator is ge

So a timeseries is being passed to the code instead of the content of the data points. You could probably extract the data from the timeseries
