Hi,
I'm porting some custom Matlab functions/scripts from 2018b to 2020b. These are used when generating C code from Simulink to an embedded target. I have a custom block in Simulink where I programmatically draw a line between an inport and Matlab Function block, and set its storage class to ImportFromFile:
set(lineHandle, 'SignalObjectPackage', 'mpt');
set(lineHandle, 'StorageClass', 'ImportFromFile (Custom)');
This code worked fine in 2018b. But in 2020b I get this error message:
"ImportFromFile" is not a valid storage class name for signals.
I have looked in the documentation but can't find any relevant information on why this is no longer working.
Best regards,

You can refer to the "Configure Code Generation Settings for Signals Programmatically” section in the below documentation link. It has detailed steps for achieving exactly what you are asking for in the R2020b version.
