MATLAB: Automatically save output variable of multiple-run simulation with different names

matlab functionworkspace

Hi,
I am running a Matlab script which opens up a Simulink model and runs the simulation several times within a for-loop. I have a Uniform Random Number Block in my model, so the output of the Simulation will be different in each run. The problem I have is that if I run the simulation 20 times via my Matlab script, the output variable is overwritten in the workspace after each run. Is there a way to save the output variable in my workspace after each run with a different name and still be able to have my script run the simulation as many times as I want automatically?
Thank you, Fabian
