Products of three triangular matrices. (English) Zbl 0933.15021
The authors show that every square matrix over a field is a product of three triangular matrices. For nonsingular matrices this result is a consequence of an earlier result of L. N. Vaserstein and E. Wheland [ibid. 142, 263-277 (1990; Zbl 0713.15003)].
