I need your help please. I’ve been trying to get dynareobc to work for a while now, but even after reinstalling Matlab and dynare I get the following error message when running the command: dynareOBC TestSolvers: ```auto +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ | Test| Solution| Solver message| +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ | Core functionalities| N/A| Successfully solved (YALMIP)| | LP| Correct| Successfully solved (INTLINPROG)| | LP| Correct| Successfully solved (INTLINPROG)| | QP| Correct| Successfully solved (QUADPROG)| | QP| Correct| Successfully solved (QUADPROG)| | SOCP| Correct| Successfully solved (FMINCON)| | SOCP| Correct| Successfully solved (FMINCON)| | SOCP| Correct| Successfully solved (FMINCON)| | SDP| N/A| No suitable solver| | SDP| N/A| No suitable solver| | SDP| N/A| No suitable solver| | SDP| N/A| No suitable solver| | MAXDET| N/A| No suitable solver| | MAXDET| N/A| No suitable solver| | Infeasible LP| N/A| Infeasible problem (INTLINPROG)| | Infeasible QP| N/A| Infeasible problem (QUADPROG)| | Infeasible SDP| N/A| No suitable solver| | Moment relaxation| N/A| No suitable solver| | Sum-of-squares| N/A| No suitable solver| | Bilinear SDP| N/A| No suitable solver| +++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++++ Warning: Unrecognized function or variable 'opti_Install_Test'. > In dynareOBCSetup (line 189) In dynareOBC (line 711) ``` ---

For DynareOBC problems, you should tag @cfp ---

opti\_Install\_Test.m should be in the Extern\OPTI\Utilities\Install directory of DynareOBC. If you do not have that directory, there is something wrong with your DynareOBC install. I suggest deleting what you have, redownloading the latest release, extracting to a folder with a short simple path (e.g. c:\dynareOBC) not some network folder, and making sure your copy of MATLAB can access the internet. ---

@cfp Thanks for the answers! I find opti\_Install\_Test.m in my path and have internet connection. It still gives me the same error message again. ---

Are you using a Mac or something? I suggest you install Gurobi or similar if your Opti toolbox install is not working for some strange reason (e.g. because you’re using a Mac…). ---

@cfp Im not using a Mac… Is it still worth a try to install Gurobi? ---

It’s always worthwhile installing Gurobi, as documented in the ReadMe and Getting Started guide. I do not understand the error you are getting. Debugging it would be helpful to me. (E.g. place a break point at line 185 of dynareOBCSetup.m and step through.) I expect it is a path issue. It would be sensible to reset your MATLAB path, then add back Dynare’s Matlab directory (do not click add with sub-folders!) and DynareOBC’s main directory (again, do not click add with sub-folders!). ---

Good you installed Gurobi! So what happens when you step through the code from there? Is the relevant Opti directory in the path at that point in time? ---

Thanks again for your help! I have added the matlab subfolder of the gurobi folder at the path. However, it still does not find the desired function. ---

I was saying you need to remove things from your path. Reset your MATLAB path and start again. ---

Could you restart MATLAB, and then paste your complete path here. (I.e. the output of the “path” command.) ---

No obvious red flags here! Other than your use of Dynare 4.6. I recommend sticking with Dynare 4.5 for DynareOBC at present. Though I really doubt that explains this issue. In any case, given your path looks fine, I expect DynareOBC will work fine. Just ignore the Opti toolbox issue. It’s irrelevant now you have installed Gurobi in any case. ---

@cfp But how do I proceed if I choose to ignore the Opti toolbox issue? ---

If you have to, you can comment out the call to opti\_Install\_Test. ---
