Figure 4-3. System Time Response to a Series of Step Signals
The (system)*(PDM) construct for performing time-domain simulation
is used analogously no matter how many inputs the system has. For a
multi-input, multi-output system, the number of rows of the input PDM
must match the number of inputs of the system. For an example of general
time-domain simulation for a MIMO system, refer to Example 4-6.
Example 4-6 General Time-Domain Simulation for a MIMO System
sys = system([0,1,0;0,0,1;-2,-4,-3],
[0,1;1,0;-1,1],[0,1,-1;1,2,1],[]);
u = pdm([sin(-3*pi:0.01:3*pi);
cos(-3*pi:0.01:3*pi)],{rows=2,columns=1});
y = sys*u;
