lyap
Lyapunov equation
Syntax
[X]=lyap(A,C,'c') [X]=lyap(A,C,'d')
Arguments
- A, C
real square matrices,
C
must be symmetric
Description
X= lyap(A,C,flag)
solves the continuous time or
discrete time matrix Lyapunov matrix equation:
A'*X + X*A = C ( flag='c' ) A'*X*A - X = C ( flag='d' )
Note that a unique solution exist if and only if an eigenvalue of A is
not an eigenvalue of -A (flag='c' ) or 1 over an eigenvalue of A
(flag='d' ). |
