3 Working with Real-Time Workshop

3-24

4 Click Apply to register your changes.

5 Generate code and build an executable: Click the Build button, type

Ctrl+B, or select Build Model... from the Real-Time Workshop sub-menu

of the

Tools menu in the model window.

6 When the build concludes, run the executable with the command

!f14rtw

7 The program now produces two message lines, indicating that the

MAT-file has been written.

** starting the model **

** created f14rtw.mat **

8 Load the MAT-file data created by the executable and look at the

workspace variables from simulation and the generated program:

load f14rtw.mat

whos tout* yout*

Name Size Bytes Class

tout 601x1 4808 double array

tout_rt 601x1 4808 double array

yout 601x2 9616 double array

yout_rt 601x2 9616 double array

Grand total is 3606 elements using 28848 bytes

Note that all arrays have the same number of elements.

9 Observe that the variables tout_rt (time) and yout_rt (G Force and Angle

of Attack) have been loaded from the file. Plot G Force as a function of time.

plot(tout_rt,yout_rt(:,2))

This plot is identical to the plot you produced in step 9 of the first part of

this exercise.
