Computing Determinants by Double-Crossing
Leggett, Deanna; Perry, John; Torrence, Eve
College Mathematics Journal, v42 n1 p43-54 Jan 2011
Dodgson's method of computing determinants is attractive, but fails if an interior entry of an intermediate matrix is zero. This paper reviews Dodgson's method and introduces a generalization, the double-crossing method, that provides a workaround for many interesting cases.
