WebA little bit of Gaussian elimination shows that the determinant of a random n x n (-1,+1) matrix is $2^{n-1}$ times the determinant of a random n-1 x n-1 (0,1) matrix. (Note, for instance, that Turan's calculation of the second moment ${\bf E} \det(A_n)^2$ is simpler for (-1,+1) matrices than for (0,1) matrices, it's just n!. It is also clearer ... WebThere are several approaches to deﬁning determinants. Approach 1 (original): an explicit (but very complicated) formula. Approach 2 (axiomatic): we formulate properties that the determinant should have. Approach 3 (inductive): the determinant of an n×n matrix is deﬁned in terms of determinants of certain (n −1)×(n −1) matrices. Webof this chapter, diﬀerent ways of computing the determinant of a matrix are presented. Few proofs are given; in fact no attempt has been made to even give a precise deﬁnition of a determinant.
