Syntax

isstable(sys)

Description

isstable(sys) returns TRUE if the LTI model sys has stable dynamics, and FALSE otherwise. For LTI arrays, isstable returns a logical array where the k-th entry indicates the stability of the k-th model.

isstable is only supported for analytical models with a finite number of poles.
