I’m having problems when following the instructions in the Initial Setup section of the MATLAB API document(AMPL MATLAB API — AMPL API 2.1.4 documentation). After running setupOnce, I go on to the firstExample function without specifying solver. Then I got the following result.
Then, after I request the MINOS and update my license, I specified the solver minos like firstExample(minos), and I got
I tried to use another solver IPOPT, but it seemed that IPOPT cannot be invoked.
I don’t know where I went wrong, could you please tell me how to deal with this problem? Thank you very much.
