(1) I have no idea how to use Microsoft Fortran Power Station (which I do not even know what it is).
(2)
- If you want the R (only) factor of the QR factorization: CGEQRF or ZGEQRF.
- If you want to solve a Linear Least Squares with a QR factorization: CGELS or ZGELS.
- If you want the Q factor and the R factor of the QR factorization: CGEQRF+CUNGQR or ZGEQRF+ZUNGQR.
If you want to do something else with the QR factorization, let us know.
The interface of the routine is given at (for example):
http://www.netlib.org/lapack/explore-html/zgeqrf.f.html
You can also find a fairly clear description of the routine in the header file.
Good luck with Microsoft software.
Julien.
