List of different Grid Types

This example is supposed to simply demonstrate the available grid, boundary and basis function types.

First, we include the meta-header sgpp_base.hpp, which includes itself all headers from the base module and set a few parameters.

#include <sgpp_base.hpp>
int main() {
size_t dim = 2;
size_t level = 3;
size_t polyDegree = 4;
sgpp::base::Grid* grid;
