Hi, assume that ı have a circuit like in the attachment and I want to control switch according to voltage difference of 2 sources. I wrote some code but apparently it is wrong. Please help me. Thank you.

You do not do anything with output "m" of "ideal switch" block ?
 

Not sure about other issues, but inside the function switchcontrol you have a time dependent expression, and your external sources "Pulse generator 1-2" are supposed arrays of values in the time domain as well, so that would result in an output dimension of 2, which is meaningless. I would only expect exclusively a mathematical operation at this box ( the array is already present at inputs ).
 
Thank you for answers. What else can ı do to control switch in simulink via m-file? I need to hear your ideas urgently.
Thank you.
