 ## Type `Diagonalizer` (`diagonalizer.hpp`), class to diagonalize symmetric Matrices
 1. Members:
    - `std::vector<double> ev(std::vector<double> mat, size_t N)`:
+
    returns eigenvalues of the symmetric matrix mat of linear size N
+
    throws upon diagonalization failure
    - `std::pair<std::vector<double>, std::vector<double> > evv(std::vector<double> mat, size_t N)`:
+
    returns pair of (eigenvalues, eigenvectors) of the symmetric matrix mat of size N
+
    throws upon diagonalization failure
