In Matlab 2019, 2020, or 2021, can parallel computing be used with intlinprog?

Some course material from 2018 shows that parallel computing applies to many optimization solvers, but not "intlinprog".

Can intlinprog be parallelized in any of the subsequent versions 2019, 2020, or 2021?

Does parallelization require a separate toolbox?

No, there is no provision for parallel computation in intlinprog. You can always check the Release Notes to find what has changed.

Thanks Alan.

I was not confident that my being unable to find something in the release notes means authoritatively that a capability is actually absent. I've gotten notification in the past that an issue I reported was resolved, and was referred to release notes, but I couldn't find anything about it there. I sent an email requesting clarification, but I sent it to the email address from which the notification was sent. I never got a response. It just hasn't percolated high enough in my priorities to follow up further.

If you want to know if a function supports parallel computing (or C/C++ code generation, or GPU arrays, etc.) look for an Extended Capabilities section near the end of its documentation page. If that section exists check if it says the function has Automatic Parallel Support. For instance, the fsolve function's documentation page lists that support while the intlinprog function's documentation page does not.

You could also filter the main function reference list by the Extended Capability and Category. When I do this for Optimization Toolbox I see 8 functions with automatic parallel support.

That is so helpful. Thanks Steven.

In case anyone else happens by this thread, the Category list on the left doesn't warp you to the homepage for the listed toolbox (which is fine for me because I don't want that). It's just a filter selection.

Futhermore, there are two nested scroll bars on the left navigation pane. Additional filters (not by toolbox) are found buy scrolling down using the outer toolbar.
