If I sweep the frequency of a AC voltage source during a transient simulation, I can see that my node voltages are have dimensions of time and the number of frequencies I use. I however cannot seem to access the 2D array in any sane way. In original qucs, I could access an entire row or column via something like a = timeSeriesSweepData[:,1] but this throws an error in QucsStudio. Specifically the error is “Wrong index for ‘timeSeriesSweepData’ in equation “timeSeriesSweepData[:,1].” How does one appropriately access 2D arrays?
