5. Run the make_quake_xyz.m script (click on Debug | Run in the Editor menu bar or on the Run icon in the
Editor tool bar) to generate the earthquake wave. This will generate a plot similar to Figure 4.1. The desired
acceleration and recorded earthquake acceleration is shown in the top plot (in gravitational units) and the
scaled position setpoint in the bottom plot (in centimeters).

Note:
The desired acceleration, which is computed from the scaled position setpoint, is the same as the
actual recorded acceleration of the earthquake, a.
6. After running make_quake_xyz.m with the files NGA_no_1806_SYL090.AT2, NGA_no_1806_SYL360.AT2,
and NGA_no_1806_SYL-UP.AT2 at x_max = 2.5 cm, the following output will be displayed in the Matlab Com-
mand Window for the x-axis:
