Re: Another python software
Thanks, Vaclav for this pointing out. In this case, I'd like to call PeriodicPythonRunner in my .cpp file. But the function/command to give as input to PeriodicPython runner would have to be in python, e.g. 'AddPlotData'. Could you tell me how to do that please?
PeriodicPythonRunner(virtPeriod=3e-5/strainRateTension,realLim=5,command='addPlotData()',label='plotDataCollector'),
Also, since I want to use my CvxOpt when 'required' and not governed by time, what do I give as input to virtPeriod?
Yours,
Boon
