Hi,

I am looking for a complex version of the rank k update ?sfrk, like dsfrk is available for doubles. I would have assumed this would be available as zsfrk, but it is not.

I did find zhfrk, but this performs a Hermatian operation which is distinctly different from a traditional transpose. I understand that dhfrk does not exist due to the banality of conjugating doubles, but zsfrk (if it existed) would have a distinct mathematical sense and application.

I could simply use the full matrix format zsyrk, but then I miss out on fully packed formats. I just think it's weird that the type-independent uniform interface was not respected for this routine, so I wanted to ask about it. Maybe I am missing something after all.

Moreover, if possible I was looking into a rank 2k update with two different alpha's (no longer making it a rank 2k update but anyway).

C = alpha x A' x B + beta x B' x A + gamma x C

If this formulation is in some way available through other function calls or combinations, I would be very grateful

Jonas
