Printing Eigenvectors and Eigenvalues to a text file

Roofit and RooStats

Hi all, so currently I am doing something like this:


//Cnn is defined above

  TMatrixDEigen me(Cnn);
  TVectorD eigenvalues=me.GetEigenValues();
  TMatrixD eigenvec=me.GetEigenVectors();

ofstream myout;
myout.open("EigenValues.txt");

myout<<"Eigenvalues are"<<endl;
myout<<eigenvalues.Print()<<endl;

myout<<"Eigenvectors are"<<endl;
myout<<eigenvec.Print()<<endl;

myout.close();

This does not seem to work, Any ideas would be appreciated!

What do you get in the txt file ?

Print() uses standard output, so will have to redirect it
