% ------    General Initializations  -------
Ts = 0.20;                   % Sampling period (in seconds)
samples = 300 ;              % Number of samples to be simulated

% ----- Neural Network Specification ------
% "nnfile" must contain the following variables which together define
% the network model:
% NN, NetDeff, NetDefg, W1f, W2f, W1g, W2g
% (i.e. regressor structure, architecture definitions, and weight matrices)
nnfile = 'forward3';         % Name of file
