Generalized singular value decompositions: a proposal for a standardized nomenclature
Bart L. R. De Moor, Gene Howard Golub · 1989
An alphabetic and mnemonic system of names for several matrix decompositions related to the singular value decomposition is proposed: the OSVD, PSVD, QSVD, RSVD, SSVD, TSVD. The main purpose of this note is to propose a standardization of the nomenclature and the structure of these matrix decompositions.
