    Ah, got it. This seems relevant - Or some related light reading here - https://ntrs.nasa.gov/citations/19970022700

    Something like this https://ksp-kos.github.io/KOS/tutorials/pidloops.html ?

    Sorry for the delay, out of town for a bit. I've checked, and the 2 MA files I posted earlier now seem to work. Also tried out the number of parallel threads and it seems good - both from checking task monitor as well as seeing that init sped up pretty noticeably. Thanks for both of those.

    For me it is maybe 5 seconds? From the output window - (15:11:50) Beginning mission script optimization... (15:11:54) Iteration Fcn-Count f(x)-Value Feasibility Optimality Norm. Step (15:11:54) 0 8 8.31191e+07 3.54e+15 NaN NaN

    hmm, weird. For my setup, I just loaded the file and hit control-R. After a step or two it gave the error. Let me know if there's anything other info I can grab to help repro it.

    MA file for the RAAN problem - http://www.mediafire.com/file/y3bmpcs3bh5zia9/file For me a simple ctrl+R shows the problem, as does ctrl+O then optimize. Another one I just found, this time an example of "Subscript indices must either be real positive integers or logicals." MA file - http://www.mediafire.com/file/fo4y7zf50rnzm8y/file log - http://www.mediafire.com/file/yddjsu077083htu/file For either of these, it could be that I'm doing something wrong so appreciate you taking a look. And thanks for the explanation about the Arg.Pe. question. Makes perfect sense.

    First off, continued thanks for developing KSPTOT - it is a huge help with KSP and even when I'm taking breaks from KSP is it fun to watch the cool improvements in TOT itself. Quick bug report - if I enable optimization for RAAN in the initial states in MA, the optimizer hangs on the "Please wait while the optimizer initializes..." popup and I get an error ding from windows. Clicking X on the popup lets me return to the MA windows. Another which might be a misunderstanding on my part - putting a number into Arg.Peri. in the initial states "edit state" pane and then saving will add it to the true anom. field and reset the Arg.Peri. to 0. Not 100% an expert on orbital mechanics so this could easily be me not knowing what I'm doing. Finally, a request - for parallel workers, let us set the number to start. My issue is that I'm running on a 3900x, and starting up 24 parallel workers takes a good bit of time and memory. I imagine that's well down on the diminishing returns curve, so starting 8 or so might be just as good and not take nearly as long? Again, thanks for all the cool work here, appreciate it.

    Yep, figured that something like that was the case. It wasn't a complaint, just something to explore that might explain what might be going on - see if waiting a bit makes KSPTOT show up.

    I noticed that it does take a long time for KSPTOT to show up the first time I run a new version. Maybe check task manager to see if it is showing up and using CPU time even if the splash screen or gui doesn't show up for a while?

    I re-uploaded it and it now shows as ~338KB. Hopefully that fixes it. Link is the same as before.

    https://drive.google.com/open?id=0B8hPVHrmVeDgNnJWbG9iWGo0ZG8 Hopefully I set sharing correctly on the link. Using the file as-is I can either ctrl-O, "Optimize Mission" or just ctrl-R when parallel is turned off. Turning it on gives the error.

    First off, thanks for the tool. It has been really useful for all sorts of crazy missions - at least when I fail I know I was trying something impossible I'm having an issue in the mission architect after enabling Script->Execution Settings->Parallelize Script Optimization. I have an existing set of constraints which run fine but after enabling parallel optimization I get "There was an error optimizing the mission script : Subscript indices must either be real positive integers or logicals" Tested with the latest prerelease linked at the top of the page. I can upload my .mat file if it turns out to be a unique problem - let me know if you can't reproduce it.

    Oh, and one more while I'm thinking of it. Looks like the issue is f(x) going from positive to negative and messing up the middle chart in the Mission Optimizer window. I get this warning early on : Iter F-count f(x) Feasibility optimality step 0 13 -1.818768e-03 0.000e+00 3.318e-01 1 26 3.140060e-03 3.620e+00 8.329e+02 6.792e-02 Warning: Negative data ignored > In optimplotfval>plotscalar (line 48) In optimplotfval (line 24) In ma_OptimOutputFunc>generatePlots (line 76) In ma_OptimOutputFunc (line 22) In ma_ObserveOptimGUI>@(x,optimValues,state)ma_OptimOutputFunc(x,optimValues,state,handles,problem,celBodyData,recorder) (line 76) In callAllOptimOutputFcns (line 13) In barrier>callOutputAndPlotFcns In barrier/nlpInterfaceFcn In barrier In fmincon (line 796) In ma_ObserveOptimGUI>executeOptimProblem (line 93) In ma_ObserveOptimGUI>ma_ObserveOptimGUI_OpeningFcn (line 78) In gui_mainfcn (line 220) In ma_ObserveOptimGUI (line 42) In ma_MissionOptimizerGUI>optimizeMissionButton_Callback (line 577) In gui_mainfcn (line 95) In ma_MissionOptimizerGUI (line 42) In matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)ma_MissionOptimizerGUI('optimizeMissionButton_Callback',hObject,eventdata,guidata(hObject)) In uiwait (line 81) In ma_MissionOptimizerGUI>ma_MissionOptimizerGUI_OpeningFcn (line 78) In gui_mainfcn (line 220) In ma_MissionOptimizerGUI (line 42) In ma_MainGUI>optimizeMenu_Callback (line 875) In gui_mainfcn (line 95) In ma_MainGUI (line 42) In matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)ma_MainGUI('optimizeMenu_Callback',hObject,eventdata,guidata(hObject)) 2 39 1.890565e-03 1.947e+00 1.829e+02 5.516e-02 Then at iteration 21 f(x) goes negative again. At that point the Current Function Value chart stops updating even though everything else keeps working. Looks like just a cosmetic bug but figured I'd mention it.

    I'm using the latest 1.5.6 prerelase 3 and get the following when I try to enable script->parallel. Anyone have ideas of what might be wrong? I'm using the Win64 MCR linked in the first post (MCR_R2015b_win64_installer.exe). Error using parpool (line 103) 'size' is not the name of a profile. Valid names are: local Error in ma_MainGUI>parallelizeScriptOptimizationMenu_Callback (line 1361) Error in gui_mainfcn (line 95) Error in ma_MainGUI (line 42) Error in matlab.graphics.internal.figfile.FigFile/read>@(hObject,eventdata)ma_Ma inGUI('parallelizeScriptOptimizationMenu_Callback',hObject,eventdata,guidata(hOb ject)) Error while evaluating Menu Callback
