Hi there, I have some simulink problem. Lets say I have a transfer function like this:

az^-1 + bz^-2 +cz^-3

The initial value of a,b,c are 0.1 0.2 0.3. I would like to change the value to 0.4 0.1 -0.5 at the nth iteration step. How to do I do it? How to I code the simulation time in simulink so that I can write "if the time > 70, a = 0.4, b =0.1, c= -0.5? Thanks.

You need a Clock block to provide the time.

But how do I quote the outputs of the clock so that I can write the following:

If clocktime < 70

a = ..
b = ..
c = ..
.
.
.
.
j = ..

else

a = ..
b = ..
c = ..
.
.
.
.
j = ..

end

Thanks
