MATLAB: Is it possible to have a generic bus selector

Question

while selecting the signal from bus selector, we need to go bus selector parameter and need to select the required signal manually. I want a bus selector to be a part of a masked subsystem. The signal to be selected by the bus selector will be given through masked parameter. For e.g. I have two signals 'a' and 'b' as input to bus selector. I will mask this subsystem and will give a mask parameter 'Which signal to select'. User can give either 'a' or 'b' and accordingly bus selector should select the signal. Is it possible? I am using matlab2006b.

Thanks in advance.

Answer 1

Check Signal Routing\Slector block. It also does the same thing.

Set Index Option as Index vector (dialog) and enter the bus element index value which is to be selected.

[Edited 19 June 2012]

get_param('BusSelectorBlock','InputSignals')

returns the name of the signals present in the bus which is input to the bus selector block and...

set_param('BusSelectorBlock','OutputSignals','SignalName')

sets the signal to be selected as output of bus selector.

Using these two commands in the callbacks of your masked subsystem, you can implement your requirement.
