Hi,
So I have a SIMULINK model which has a MPC controller made from the MPC toolbox block and it works perfectly fine in SIMULINK. My question is how do I get the computation time of this MPC block in SIMULINK? (So like in MATLAB script, quadprog gives you compuation time, is there a way to get the same time for the MPC toolbox block?).
Thanks a lot for your help.

tic;
sim(Model_name);
toc;
tic/toc functions are like stopwatch to measure the time. You can use sim() to run simulation of a Simulink model at the command line.

Hi,
I think this will just measure total time of simulation. I want just computation time for each time step of the simulation. Like if my discrete solver time step is 0.1s, the MPC will have a certain computation time for each of these 0.1s ticks of the solver.

If you're trying to analyze the performance of your Simulink model (to identify bottlenecks?) consider using Simulink Profiler.

This can help me in like a simulink only simulation, so this is a good start.
But, Is simulink profiler like code generateable ? Like I want to compile this model I have into a C++ code for some other hardware to get computation time of the MPC block. Will this profiler work on another hardware ?
