Howdy, I am using Simulink (R2010a)

I am using a "For Loop Subsystem" to do recursive matrix calculations. For i = 1 to 8.

Once I got all the calculations correct, I put the whole thing inside a "Triggered Subsystem" .

Now the "For Loop" only executes once. For i = 1 to 1.

Has any one else seen this? Does anyone have suggestions.

Thanks.

I think I remember someone saying that a "for loop subsystem" takes as many time-steps as the number of loop iterations, but that when you are in a triggered subsystem, you only give it the one timestep of the trigger. You would need to trigger-and-hold or something like that.
