Hello,

I hope this is a legitimate question, unfortunately I am unable to attach the MATLAB files.

I am using in my code the function "optimoptions" in the following way:

opts = optimoptions('quadprog','Algorithm','interior-point-convex','OptimalityTolerance',1e-8,'ConstraintTolerance',1e-8);

and I recieve the following error:

Error using optimoptions (line 124)
Invalid solver specified. Provide a solver name or handle (such as 'fmincon' or @fminunc).
Type DOC OPTIMOPTIONS for a list of solvers.
Error in compute_NE (line 78)
opts = optimoptions('quadprog','Algorithm','interior-point-convex','OptimalityTolerance',1e-8,'ConstraintTolerance',1e-8);

I know the code works (my collaborator was able to run it easily, but he has a much older version of MATLAB, while I have the 2024b)

I believe that due to verison upgrade, the behavior of either "quadprog" or "optimoptions" has changes, and thus I am unable to run it.

How can I ensure "optimoptions" treats "quadprog" as a solver?

Thank you in advance for your time and cosideration.

Nope. Whatever is happening it is only on your computer. If we run it here in the online environment (R2024b), it works fine:

opts = optimoptions('quadprog','Algorithm','interior-point-convex','OptimalityTolerance',1e-8,'ConstraintTolerance',1e-8)
opts =

Huh, I assumed that MATLAB Answers and MATLAB Online had been updated to R2025a, but it looks like they have not been!

Good thing. We've been seeing lots of problems with R2025a.

Hey @Elinor Ginzburg,

A similar issue was observed when generating a standalone executable for a script that uses the "contopptraj" function from the Robotics System Toolbox. This specific bug has been resolved in R2024b. Further details are available in the following external bug report:

Make sure that the Optimization Toolbox is installed correctly or try reinstalling it. The "ver" command can be used to check the installed toolboxes.

Sharing additional information about the workflow, the versions involved, and clearer reproduction steps would assist the community in providing more focused support.
