Automating Signal Storage Class in M script

How do I specify the storage class for a signal in m script? I would like to automate this process. For example, under signal properties-->RTW-->Storage Class....I would like to set the signal to Imported Extern.

Thanks in advance!

If you already have a Simulink.Signal object associated with the relevant signal line, then you can use code similar to what Titus suggested (just switch Simulink.Parameter with Simulink.Signal). But if you just want to operate directly on a named signal, and have the handle to the signal, you can set it using the "RTWStorageClass" property. For example, using a demo model called "busdemo":

open_system('busdemo');
ph = get_param('busdemo/Bus Creator', 'PortHandles');
set(ph.Outport, 'RTWStorageClass', 'ImportedExtern');

(The last line will error out if you do not have a signal name, in which case you may set that using the SET command for the SignalName property)

Hi Brandon,

you set the properties with "dot" notation:

x = Simulink.Parameter;
x.Value = 2.0;
x.RTW.StorageClass = 'ImportedExtern';

The last command is probably not completely correct, because I have no MATLAB here to test ... The easiest is to typ x. and then Tab to get the list of "allowed" names.

Perfect; thank you for both answers. I had just previously used Titus's example for creating globals for calibrations in my workspace. Kaustubha's answer is exactly what I'm looking for. Thanks again to the both of you

Hi Brandon, sounds good. I would suggest to mark the question answered (by Kaustubha)...
