I’m having some issues with QR factorization in Julia 1.0. I want to efficiently compute the QR factorization of the transpose of a matrix and save only Q. Back in 0.6, there were LAPACK functions that did this efficiently and in-place. Now, it looks like I’m stuck with
qr! does not accept transposes or adjoints, and the seemingly efficient LAPACK functions require a
tau argument which I’m confused about.
Any help is appreciated.
