For e-vals and e-vectors it's pretty advisable to use LAPACK. One could say they set the standard regarding eigensolvers. They are originally written in Fortran, but you can call them in C, there is no need to rewrite everything in Fortran, if you you already have a working code in C.
I am going to do HPC, but before that I want my program be as fast as possible. Even when doing HPC, the whole procedure will be slow enough, so I need a faster numerical library which calculates eigenvalues and eigenvectors with great performance. What is the fastest numerical library in C++? Or should I quit C++ for faster numerical calculations and switch to Fortran?
Any help will be appreciated,
Regards
Nadir
