What is the name of the transformation H = I - 2vv^T (where v is a unit vector) used to reflect a vector across a plane?
Show answer
Householder transformation
Householder transformations are more numerically stable than Gram-Schmidt for performing QR decomposition. They are reflections rather than projections, preserving the norm of the vectors they transform.
