3
abcd - state-space matrices
8
sl : linear system (syslin list) in state-space or transfer form
10
A,B,C,D : real matrices of appropriate dimensions
13
returns the A,B,C,D matrices from a linear system Sl.
15
Utility function. For transfer matrices Sl is converted into state-space
18
The matrices A,B,C,D are the elements 2 to 5 of the syslin list Sl, i.e.
22
A=diag([1,2,3]);B=[1;1;1];C=[2,2,2];
23
sys=syslin('c',A,B,C);
26
[A1,B1,C1,D1]=abcd(sys);
