Function File: sys = sminreal (sys)
Function File: sys = sminreal (sys, tol)

Perform state-space model reduction based on structure. Remove states which have no influence on the input-output behaviour. The physical meaning of the states is retained.

Inputs

sys

State-space model.

tol

Optional tolerance for controllability and observability. Entries of the state-space matrices whose moduli are less or equal to tol are assumed to be zero. Default value is 0.

Outputs

sys

Reduced state-space model.
