Function File: bool = isstable (sys)
Function File: bool = isstable (sys, tol)

Determine whether LTI system is stable.

Inputs

sys
LTI system.
tol
Optional tolerance for stability. tol must be a real-valued, non-negative scalar. Default value is 0.

Outputs

bool
True if the system is stable and false otherwise.
 
   real (p) < -tol*(1 + abs (p))    continuous-time
   abs (p) < 1 - tol                discrete-time
