Hi all, I made a Simulink model that incorporates a certain given block, as well as a matlab function I wrote myself. The given block demands that the time step will be 0.001 secs, but the function (using tic/toc) takes close to 0.003 secs to calculate.
Does anyone know the mechanism behind this? should I use a rate transition block before and after the function? Or is it OK to leave it as-is?
Thanks in advace, Tim

Hi Tim,
Simulink does not simulate in Real-Time. So if a step of 1s of simulation time takes 0.01s of computer time or an hour does not make a difference (accept with regards to the patience you need).

Thank you,
The model runs on external mode with real-time HIL blocks. I just let put them all together and it worked nicely (certain errors with specific arrangements but I managed to avoid them).
