double nnDSigmoid (  nnNode *    node )

Derivative of the sigmoid function. Parameters: node  The nnNode to calculate the sigmoid derivative for. Returns: Sigmoid derivative calculated from node->in.

void nnGetNetworkOutputs (  nnNet *    net, double    outputs[] )

Stores the states of all output nodes in a network into an array. Parameters: net  Network with output states to get. outputs  Array where to store outputs.

void nnRunNetwork (  nnNet *    net )

Evaluate each successive layer of a network, from input to output. Parameters: net  Network to evaluate.

void nnSetNetworkInputs (  nnNet *    net, const double    inputs[] )

Set the input nodes of a network from an array. Parameters: net  Network with inputs to set. inputs  Array of from which to set the inputs.

double nnSigmoid (  nnNode *    node )

Sigmoid function. Parameters: node  Pointer to the nnNode for which to calculate the sigmoid value for. Returns: Sigmoid value calculated from node->in.
