eigen/doc/snippets/HouseholderQR_solve.cpp
Benoit Jacob e093b43b2c * rename QR to HouseholderQR because really that impacts the API, not just the impl.
* rename qr() to householderQr(), for same reason.
* clarify that it's non-pivoting, non-rank-revealing, so remove all the rank API, make solve() be void instead of bool, update the docs/test, etc.
* fix warning in SVD
