Complex equivalent to DORGQR??

Postby kdallen » Fri Mar 30, 2012 5:47 pm

Maybe a silly question, but is there an equivalent routine to DORGQR for complex numbers? There are equivalents to DGELS, DGGLSE, DGELSD, etc., but not one to explicitly create Q and R matrices. There must be an obvious reason.

Thanks, Ken

Are you looking for ZUNGQR? For complex matrices, the analog to ORthogonal is UNitary.
