Examples of AbstractFunction

ca.nengo.math.impl.AbstractFunction
Base class for Function implementations. The default implementation of multiMap() calls map(). This will be a little slower than if both methods were to call a static function, so if multiMap speed is an issue this method could be overridden, or it might be better not to use this abstract class. @author Bryan Tripp

Represents a function
com.opengamma.engine.function.AbstractFunction
