-# Data sets from experiments
-
-## Open-loop experiment
-
-Here we provide the data from the open-loop experiment `software/quanser_updated/q_as_ol.slx`. 
-Load the data into Matlab workspace using
-
-```matlab
-load measured_and_simulated_open_loop_responses.mat
-```
-
-Two new data structs then appear in the workspace
- 
-- `measured_ol_response`
-- `simulated_ol_response`
-
-Plot these using
-
-```matlab
-figure 
-plot(measured_ol_response.time, measured_ol_response.signals.values)
-figure
-plot(simulated_ol_response.time, simulated_ol_response.signals.values)
-```
-
-See the corresponding Simulink file for the meaning of the stored variables.
