How can I select the output of WaveFormGenerator Simulink block from a script?

Hello,

I am using the block WaveFormGenerator from simulink, I see that the Output Signal can be selected during the simulation according to the documentation, so I was wondering whether or not it is possible to select that output from a initial script that will launch my simulation.

Any suggestions if this is achievable?

Thanks in advance,

I understand that the Programmatic (command-line) way to select a signal output of a WaveFormGenerator is being asked for.

It is possible to select signals before the simulation starts and after a simulation has ended but not during the time when simulation is running.

By using the 'get_param' one can change and select signals as required. Following is a code snippet on how to do so:

>> WaveFormBlk = gcb %path to the WaveformGenerator block in model (Can select the block and use gcb or give the ExactPath to the block as a string)
>> get_param(WaveFormBlk,'selectedSignal')
% returns the present selected signal
>> set_param(WaveFormBlk,'selectedSignal','4') 
% Change the selection to 4, Third argument has to be a string containing a number representing which signal to select

Hope this helps!

Thanks Kushagr Gupta, I wasn't aware of the gcb function!
