Thread Subject: Plot a signal from simulink v.s. time step index

Hello,

1. Does anyone know how to plot a signal generated by
Simulink (FixedStepDiscrete solver) versus time step
index?

2. Does anyone know how to query to get the simulation
time step size for a model with FixedStepDiscrete
solver?

3. Does anyone know if there is a way to display
multiple signals on one page for signals generated
in 1 and with a cursor in there for all of them?

Thanks,

Mike

Hi Mike,

1. The best and easier way is to save data in workspace,
then you can plot it vesus Time Step Index.

2. To get the simulation option structure use the
command 'simget'. Example:
>> simget('untitled','FixedStep')

3. You can display multiple signal using the block 'mux'.

Pedro

Yes, it would be nice if Simulink has block that can
automatically does all this.

Yes, but it just returns whatever I set in the Solver
pane for Fixed-step size field. If it is 'auto', I expect
to get the actual step size used by the simulator, however,
it just literally returns the string 'auto'.

Yes, however, I wish to have a cursor that will give me
the step index and the vaule of the signal at that step.
