Dodgson condensation Dodgson condensation In mathematics, Dodgson condensation is a method of computing the determinants of square matrices. It is named for its inventor, Charles Lutwidge Dodgson (better known as Lewis Carroll). The method in the case of an "n" × "n" matrix is to construct an ("n" − 1) × ("n" − 1) matrix, an ("n" − 2) × ("n" − 2), and so on, finishing with a 1 × 1 matrix, which has one entry, the determinant of the original matrix. This algorithm can be described in the following four steps: One wishes to find We make a matrix of
