public class IntegrationNeuralFunction
extends NeuralFunction

Integration function.

Leaky integrator function.

The input is amplified and integrated, and slowed by a slowing factor. If the input is infinity then zero is output. However, if IgnoreInfinity is true, then the previous output is returned. Or, if EnableInfinity is true, then infinity is output. If the output is infinity, and the input returns to a real value then the output is set to the reset value, which is either zero or the value from a link, if configured.

The configuration parameters to the function are as follows:

Gain - the amplification factor (type Double). Mandatory.
Slow - the slowing factor (type Double).
EnableInfinity - true or false (type Boolean).
IgnoreInfinity - true or false (type Boolean).
