Hi, how to extracted a linear model from the nonlinear neural NARX using Instantaneous Linearization in MATLAB?, there is any command for doing Instantaneous Linearization for NARX in MATLAB? please help me. thanks.

For linear models
net = feedforwardnet([]);
similarly
net = narxnet(ID,FD,[]);
NOTE: for obsolete functions (e.g., newff) the empty bracket may have to be replaced by the numeral 0.
Hope this helps.
Thank you for formally accepting my answer

Thank you for answer my question, I have obtained narx model with 4 inputs (u(t-1), u(t-2), y(t-1), y(t-2)) and 1 output with function (newff), and i have generate Simulink block for neural network simulation, can i used this last with model predictive control Toolbox?. thanks.
Sorry, I am not familiar with predictive control.
Aren't you worried about mixing the obsolete function newff with the current function narxnet?
