Simulate nonlinear ARX model in Simulink software

**Library:**System Identification Toolbox / Models

The Nonlinear ARX Model block simulates the output of a nonlinear ARX
model using time-domain input data. The model is an `idnlarx`

model that you previously estimated or constructed in the
MATLAB^{®} workspace. You specify initial conditions for the simulation as either
steady-state input and output signal levels or as an initial state vector.
