I have signals in a SIMULINK bus and I would like to select specific signals from it. The issue is that I want to run an initialization script that will decide which subset of signals to select. I see that you can select bus signals manually via the bus selector block. Is there any way to perform this function programmatically?

Hi,

You can select the signals to be passed through the bus selector by using:

%Say we want to choose the signals 1 and 2 to pass through the Bus
%selector, then we can do:
set_param(gcb,'OutputSignals','signal1,signal2')

Here gcb contains the name of the block i.e. in my case:

>> gcb
ans =
    'trial/Bus Selector'

where 'trial' is my model's name. I hope this helps! More information on Bus selector can be found here:Bus selector block (check the Programmatic Use sections)
