Examples of BinaryFunction

javaff.data.metric.BinaryFunction
nexj.core.meta.BinaryFunction
Interface implemented by functions of two arguments.
org.apache.mahout.math.function.BinaryFunction
This interface allows the formulation of binary functions to be applied to matrices inside the inner loops of their implementations.
