The trajectory traced during simulation is shown in red. Note that it traverses both the
stable and unstable regions of the scheduling space. Suppose you want to implement this
model on a target hardware for input profiles similar to the one used for simulation
above, while using the least amount of memory. The simulation suggests that the
trajectory mainly stays in the 890 to 1200 m/s range of velocities and -15 to 12 degree
range of incidence angle. Furthermore, you can explore increasing the spacing between
the sampling points. Suppose you use only every third sample along the dimension and
every second sample along the dimension. The reduced system array meeting these
constraints can be extracted from G as follows:


I1 = find(alphaRange>=-15pi/180 & alphaRange<=12pi/180);
I2 = find(VRange>=890 & VRange<=1200);
I1 = I1(1:2:end);
