Online/Incremental Learning (Neural Network) with S-Function

I would like to train/adapt my neural network online/incremental. I'm using S-Function in Simulink to realize.

While running the Simulink simulation i got an error in flag=3(output). "adapt" is a undefined function. Same error for function "train".

An error occurred while running the simulation and the simulation was terminated

Caused by:

• Error in 'Sim_RNNOnline/S-Function' while executing MATLAB S-function 'RNNOnline', flag = 3 (output), at time 0.0.
• Undefined function 'adapt' for input arguments of type 'double'.

Do I need any Toolbox for S-Function to use "train" or "adapt"? Is there any other option to "adapt" my neural Network incremental/online?

hi.

I have question.

if i have my trained neural network in mat file. how can i use it in my simulink model? using matlab function of S function.
