A note on symplectic block reflectors. (English) Zbl 1171.65038
Summary: A symplectic block reflector is introduced. The parallel with the Euclidean block reflector is studied.
Some important features of symplectic block reflectors are given. Algorithms to compute a symplectic block reflector that introduces a desired block of zeros into a matrix are developed.
