Finding the eigenvalues of a complex matrix

[jezza10181]

Hi,

I am aware of the implicit QR algorithm, which utilises the 'Francis QR step' to find the eigenvalues of a real, square matrix.

But, how would one find the eigenvalues of a complex matrix? Would the 'explicit' version of the QR algorithm be used here, using complex arithmetic?

Thanks

maybe if you explain what you do know, someone will see how to generalize it.
