Hello Rajeev,

The variable "P" is undefined in your Fcn block.

Define the value of the variable "P".

I defined the P variable but same error displayed again.

Hi,

Is it the same error? Isn't it a different error message?

I seem to have the wrong number of elements in your Fcn block. Since the output of the Demux block is scalar, I don't think u (2) or u (3) can be used.

I think the input of the Fcn block can remain a vector. I have attached a reference example.
