Interface LinearFitterMultiDimensionFunctionEvaluator

public interface LinearFitterMultiDimensionFunctionEvaluator
Interface to evaluate linear multidimensional functions f(x1, x2, ...) = a * f0(x1, x2, ...) + b * f1(x1, x2, ...) + ... Where the linear function is composed of a linear combination of a basis of functions f0, f1, ... fM For each evaluation at a given point (x1, x2, ...), this interface will return an array containing the evaluations of the basis functions at such point f0(x1, x2, ...), f1(x1, x2, ...), ..., fM(x1, x2, ...)
