ADiGator & GPOPS-II

[John Ash]

Hello,

I'm attempting to use ADiGator on my GPOPS-II simulation, instead of SparseCD.

From the GPOPS-II documentation, after installing ADiGator, I should only have to change/add the following line:
setup.derivatives.supplier = 'adigator';

However when I run my program I get the following error:
"Error using gpopsVerifySetup (line 3675)
GPOPS-II ERROR: AdiGator could not produce derivative files"

Using the documentation I then follow up with running the following command:

adigatorGenFiles4gpops2(setup)

Which produces the following output:

Warning: File not found or permission denied

In adigator at 79
In adigatorGenFiles4gpops2 at 200
Transforming User Function: 'Endpoint'
Taking Derivatives wrt: 'v'...
Subscripted assignment dimension mismatch.

Error in adigatorCellStrucAsgn (line 136)
ADIGATOR.VARINFO.NAMELOCS(PreOpCount:ADIGATOR.VARINFO.COUNT-1,2) = ...

Error in adigatortempfunc1 (line 190)
output.eventgroup =
adigatorCellStrucAsgn(16,adigatorDummyStruc,adigatorStrucAsgn16,'output.eventgroup(number_of_gates+1).event =
adigatorStrucAsgn16;',number_of_gates+1);

Error in adigator (line 487)
FunctionInfo = adigatortempfunc1(FunctionInfo,UserFunInputs);

Error in adigatorGenFiles4gpops2 (line 200)
adigator(PointFunc,{pinput},PointDeriv1,ADopts);

Any help with where to start would be great. I can attach my code if needed.

Thanks for taking a look,

John Ash

Hi John,

This is a bug on my end in the adigatorStrucAsgn file

Lines 136 and 137 should read

  ADIGATOR.VARINFO.NAMELOCS(PreOpCount:ADIGATOR.VARINFO.COUNT-1,2) = ...
    1:ADIGATOR.VARINFO.COUNT-PreOpCount;

(there was a -1 on the RHS that was wrong)

I attached a file that has the change if you want to just replace the old one - should be located at adigator/util/adigatorCellStrucAsgn

Please let me know if you find any other issues or have any questions.

Hi Matthew, thanks for the quick turn around.

Here is the next error I found:

EDU>> adigatorGenFiles4gpops2(setup)
Warning: File not found or permission denied

FunctionInfo = adigatortempfunc1(FunctionInfo,UserFunInputs);

Error in adigatorGenFiles4gpops2 (line 200)

Would this be any easier for you if you had my files?

I appreciate your help,

Hey John,

Yeah I can't tell what is causing this just from the error message. If you could either attach your files here or send then to me at weinstein87@gmail.com I can try to figure out what's going on.

Apologies for the errors - cell and structure assignments have been a major pain on the debugging front.
