Dynare 7.x parallel computing toolbox in older MATLAB

Estimation
1

Hi Dynare

I have a quick question: I’ve got a spare older machine which can only run MATLAB up until R2024a. When I tried to use Dynare 7.x’s inbuilt parallel computing function for estimation purposes, I received an error stating that the parallel computing toolbox was not available or compatible (despite double checking and reinstalling MATLAB to verify that the PCT was installed), and it suggested I upgrade to a newer version of MATLAB.

This struck me as very strange. Is there some kind of backwards compatibility issue for Dynare 7.x’s parallel computing options and versions of MATLAB older than r2025b?

Due to MATLAB internals, you need at least R2024b. Older versions will give you the mentioned error message.

I see. Would it be possible to build in PCT backward compatibility for R2024a and older?

My understanding is that this is not feasible because some necessary features were only introduced in that Matlab version.
