How to import .dat file at 2021a version?

I was trying to use "SimulinkRealTime.utils.getFileScopeData", and noticed this was removed at 2020b.

Then, any substitute should be given, but there were nothing in the document.

Which function could I use for import ".Dat" file?

The following MATLAB Answers post contains a utility function to import File Scope data in more recent MATLAB releases such as R2020b and later.

Thank you so much for this! This is much appreciated!

Hi HyeongKeun,

In MATLAB R2020b and later, this function is no longer required because the file logging mechanism is not based on the legacy File Scope block anymore, and the .dat files you are referring to are no longer created on the target machine. Instead, a new File Log block is available, which does not require any manual data extraction. For more information, you can have a look at the following MATLAB Answers post:

Best,

This is true, but the ability to read in archived .dat files that were created with the original File Scope block should have been maintained. As it stands, the only way to do this seems to be to maintain a legacy pre-2020b version of MATLAB.

Is there anyway we can get a solution for this? I have many legacy .dat files which I need to work with... Its not ideal to have to keep 2019a arround forever for this one util funciton... Would it be possible to pack the util and it's dependancies in an optionally downloadable addon?
