two questions in matlab

[mohamed mahmoud]

firstly :
i need to implement multiplexer in matlab simulink ?
note : mux block in simulink is useful to combine signals into one vector.and i don,t this
i need to "select" only one input from all inputs and pass it (natural mux)
----------------------------------------------------------------------
secondly :
if i want to implement custom block (time amplifier), is there ability to implement it in simulink ?
note : time amplifier is useful to stretch small time difference to high time difference

1. Look for Switch under Signal routing
2. Look for Subsystem under Commonly used blocks
