Non-Linear function needed

Started by margaritis_n January 25, 2005

I am trying to simulate a chomunnication scheme in simulink. I need
to "construct" a non-linear function. I tryed the function block from
Simulink>function>Fcn but seems that it doesnt coorporate well with
if-clauses! Using the Matlab help I found that there is also an S-
function that the user can implement his own model. However the help
file doesn't say much. Can somebody help me with this S-function and
how it works with the m-files???
