WebMar 5, 2024 · Luckily, it is very easy to compute the determinants of certain matrices. For example, if M is diagonal, then Mi j = 0 whenever i ≠ j. Then all summands of the determinant involving off-diagonal entries vanish, so: det M = ∑ σ sgn(σ)m1 σ ( 1) m2 σ ( 2) ⋯mn σ ( n) = m1 1m2 2⋯mn n. WebAnswer: Simply, the determinants of a matrix refer to a useful tool. As the name suggests, it ‘determines’ things.
