LAPACK orthonormalization function

Question

Is there ready routine in lapack to perform orthonormalization, for example Gram-Schmidt or some variation of QR method?

if not, what is the advised approach to perform orthonormalization using lapack?

Answer 1

Yes, there is! Look at:

sgeqrf (single precision real)
dgeqrf (double precision real)
cgeqrf (single precision complex)
zgeqrf (double precision complex)

In general, for LAPACK documentation, consult netlib.
