functioneigenValues
Calculate the eigenvalues of a linear state space system and write them in a complex vector
Information
Syntax
eigenvalues = StateSpace.Analysis.eigenValues(ss)
Description
Calculate the eigenvalues of a state space system, i.e. the eigenvalues of the system matrix A of a state space system. The output is a complex vector containing the eigenvalues.
Example
Modelica_LinearSystems2.StateSpace ss=Modelica_LinearSystems2.StateSpace(
A=[-1,1;-1,-1],
B=[1;1],
C=[1,1],
D=[0]);
Complex eigenvalues[2];
algorithm
eigenvalues = Modelica_LinearSystems2.StateSpace.Analysis.eigenValues(ss);
// eigenvalues = {-1 + 1j, -1 - 1j}
