Simulink switch that is based on probability

How do you use Simulink to create a pathway with a switch that splits into two based on probability (for eg, 0.4 of the time goes through port A and 0.6 of the time goes through port B)?

Are you using Simevents?

If yes, this discussion might help.

This seems to work for me (The uniform random number is set to a range of 0 to 1):

Thanks so much! Looking forward to trying it but this was exactly along the lines of what I was thinking. I’m trying to create a Markov chain model similar to what is possible with TreeAge Pro

[Jim Riggs]

I'm thinking that one way to implement this in a subsystem like this:

In this case, the enabled subsystems simply pass the signal straignt through. Signals A and B are defined outside, and the subsystem simply acts a a probabilistic switch between A and B.

You can create a mask for the subsystem and set the percentage threshold (i.e. the 0.4 value) in the mask.

Thanks again! This was very helpful !!

If my answer was helpful, please accept it.Thanks.

[Jim Riggs]

Um, you accepted your own answer, not mine.

[George Jacob]

Sorry about that. I’m a nube. Hopefully I did it right this time.

[Jim Riggs]

Thank you.
