Matrix Norms
Norms on matrices can be computed in the same fashion as on vectors:
#include <iostream> #include <boost/numeric/mtl/mtl.hpp> int main(int, char**) { using namespace mtl; const unsigned n= 10; dense2D<float, matrix::parameters<col_major> > B(n, n); matrix::hessian_setup(B, 1.0); std::cout << "one_norm(B) is " << one_norm(B)<< "\n"; std::cout << "infinity_norm(B) is " << infinity_norm(B)<< "\n"; std::cout << "frobenius_norm(B) is " << frobenius_norm(B)<< "\n"; return 0; }
The norms are defined as:
