If the signal is a vector, then yes, you can use the Select block to pick any element of that vector.

saima: Like I said, your signal needs to be a vector to be able to use a Selector block. It's acts as if you are indexing into it. For example:
a = [1 2 3];
b = a(3); %This is the type of operation that Selector does
It looks like what you trying to do is get just the sample at t=FinalSimulationTime. Is that correct? Could you explain what you plan to do with this value - will it be used in MATLAB or somewhere else in the model?
