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.

Just flagging this question as answerd as part of a clean up for Matlab answers. Walter Roberson answered it in the comments above:

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
