Remove delay to neural network's response
net = removedelay(net,n)
net = removedelay(net,n) takes these arguments,
Number of delays
and returns the network with input delay connections decreased,
and output feedback delays increased, by the specified number of delays
The result is a network which behaves identically, except that outputs
n timesteps later.
If the number of delays
n is not specified,
a default of one delay is used.
Here a time delay network is created, trained and simulated
in its original form on an input time series
T. It is then with a delay removed
and then added back. These first and third outputs will be identical,
while the second will be shifted by one timestep.
