which is a modification of LINPACK's DQRDC.
But you are right, and I have added to
man for `qr` says that the function uses LINPACK's DQRDC, while it in
fact uses DQRDC2.
```
The QR decomposition of the matrix as computed by LINPACK or LAPACK.
The components in the returned value correspond directly to the values
returned by DQRDC/DGEQP3/ZGEQP3
