import data from simulink and figure it using stairs function in matlab

To import data from Simulink to MATLAB, you first need to save the data from Simulink to the workspace:

1. In Simulink, open the model that generated the data you want to import.
2. Run the simulation to generate the data.
3. In the MATLAB Command Window, type the following command:

   main.m
   simout = sim('model_name');
   28 chars
   2 lines

   Replace model_name with the name of your Simulink model.
4. The variable simout will contain the simulation output data.

To plot the imported data using the stairs function:

1. In the MATLAB Command Window, type the following command:

   main.m
   stairs(simout.Time, simout.Data);
   34 chars
   2 lines

   This will plot the data using the stairs function.
2. You can customize the plot by adding axis labels, titles, legends, etc.

Note: Make sure that the Simulink model is saved and closed before importing the data to MATLAB.
