WebMar 5, 2024 · We now know that the determinant of a matrix is non-zero if and only if that matrix is invertible. We also know that the determinant is a multiplicative function, in the sense that det (MN) = det M det N. Now we will devise some methods for calculating the determinant. Recall that: det M = ∑ σ sgn(σ)m1 σ ( 1) m2 σ ( 2) ⋯mn σ ( n).
