Purpose Form the observability matrix

Syntax Ob = obsv(A,B)

Ob = obsv(sys)

Description obsv computes the observability matrix for state-space systems. For an n-by-n

A and a p-by-n matrix C, obsv(A,C) returns the observability matrix

with n columns and np rows.

Ob = obsv(sys) calculates the observability matrix of the state-space model

sys. This syntax is equivalent to executing

Ob = obsv(sys.A,sys.C)

The model is observable if Ob has full rank n.

Example Determine if the pair

is observable. Type

Ob = obsv(A,C);

% Number of unobservable states

unob = length(A)-rank(Ob)
