thank you very much! This is a very nice and welcome addition! I'll try to investigate the failing tests in the next couple of days

@lucaferranti I'm happy is it interesting! Happy to contribute!

I am thinking about implementing Miyajima's estimates for eigenvalues later on, also.

I will also check if Miyajima's svd estimate works for complex matrices (Rump estimate works, so it should, but the theorems in his paper are only stated for real matrices.)
