Logical test for system detectability. All unstable modes must be observable or all unobservable states must be stable.
Inputs
LTI system.
State transition matrix.
Measurement matrix.
Descriptor matrix.
If e is empty []
or not specified, an identity matrix is assumed.
Optional tolerance for stability. Default value is 0.
Matrices (a, c) are part of a continuous-time system. Default Value.
Matrices (a, c) are part of a discrete-time system.
Outputs
System is not detectable.
System is detectable.
