Class R1Projection

All Implemented Interfaces:
Function<Vector,Double>, RealScalarFunction

public class R1Projection extends AbstractRealScalarFunction
Projection creates a real-valued function RealScalarFunction from a vector-valued function RealVectorFunction by taking only one of its coordinate components in the vector output. For example, suppose we have a \(R^n \rightarrow R^m\) function, \(f_1 = [y_1, y_2, y_3]'\). We construct a \(R^n \rightarrow R\) function by taking its second coordinate. That is, \(f_2 = y_2\).
