Divide block in simulink

[Didi Istardi]

Hi..

can anyone give me a way to avoid zero division in divide block in simulink..

cause i always have a problem with zero division or in singularities..

thanks

What do you expect the simulation to do when there does come a
computation with a divide by zero error occurs? I'm not sure if there
is a generic block for this - you could always use a switch that takes
in the 'denominator' and checks for a zero - if there is one, take an
alternate path or add a small offset to the denominator before
continuing on.

instead of doing a/b, you can do a/(b+realmin*sign(b))

realmin is 2.2251e-308 so it does not have any effect on any practical
division.
