MATLAB: Saving mat file with many signals from Simulink

Question

I have a Simulink model that calculates many time series (position, velocity, power, etc) in different blocks. I would like to create a single mat file containing all of these signals, either from within Simulink or from the Matlab script that I will be using to execute the simulation with the sim commmand. What is the best way to do this?

Answer 1

Save your variables from simulink to workspace using ToWorkspace block. Assign specific name to each variable.

And in your Matlab script save these variable to mat file once the simulation is over.

OR

alternatively you can use the variables save command in simulation stop callback fucntion (StopFcn) of your model as

save('MyFile.mat','position','velocity','power');

so variables will be saved automaticaly when simulation is comleted.
