Synopsis

This class forms a function of the form f(x0,x1,..,xm-1) = p0*x0 + p1*x1 +...

f(x0,x1,..,xm-1) represents a hyper plane of dimension m.

Since the HyperPlane is a Function, the derivatives can be obtained as well.

The parameter interface (see FunctionParam class), is used to provide an interface to the Fitting classes.

This class is in general used implicitly by the HyperPlane class only.

Example

// form the hyper plane function of this form:
// 6*x0 + 2*x3
HyperPlane<Double> hyper(4); // 4-dim hyperplane
hyper.parameters()[0] = 6;
hyper.parameters()[3] = 2;
// Evaluate at x0=5, x3=7
Vector<Double> x(4);
x=0; x[0]=5; x[3]=7;
cout << "Hypervalue: " << hyper(x) << endl;
Hypervalue: 44

Motivation

This class was created to facilitate linear constraint functions for the use of least-squares fits.
