dormqr for complex input?

Postby Mat » Fri Aug 17, 2007 1:07 pm

Hello,

my program uses the dormqr function with a previously computed dgeqrf QR factorization. Now i want to do the same "thing" (dormqr) with a previously computed complex QR factorization - but i can't find a method like dormqr for complex input?

Thanks for help
Mat

what about looking for zunmqr ?

(complex matrices that have the property Q^H Q = I and Q square are called unitary
so this gives ZUNxxx while real matrices that have the properties Q^T Q = I and Q
square are called orthogonal so this gives DORxxx)
