# Rn_floorNorm-class: An S4 class to represent the function... In multIntTestFunc: Provides Test Functions for Multivariate Integration

## Description

Implementation of the function

f \colon R^n \to [1,∞),\, \vec{x} \mapsto f(\vec{x}) = \frac{Γ(n/2+1)}{π^{n/2}(1+\lfloor \Vert \vec{x} \Vert_2^n \rfloor)^s},

where n \in \{1,2,3,…\} is the dimension of the integration domain R^n = \times_{i=1}^n R and s>1 is a paramter. In this case the integral is know to be

\int_{R^n} f(\vec{x}) d\vec{x} = ζ(s),

where ζ(s) is the Riemann zeta function.

## Details

The instance needs to be created with two parameters representing n and s.

## Slots

dim

An integer that captures the dimension

s

A numeric value bigger than 1 representing a power

## Examples

 1 2 n <- as.integer(3) f <- new("Rn_floorNorm",dim=n,s=2)
