In this talk we explore continuous analogues of matrix factorizations. The analogues we develop involve bivariate functions, quasimatrices (a matrix whose columns are 1D functions), and a definition of triangular in the continuous setting. Also, we describe why direct matrix algorithms must become iterative algorithms with pivoting for functions. New applications arise for function factorizations because of the underlying assumption of continuity. One application is central to Chebfun2.
