Det of inverse matrix
WebHow do I find the determinant of a large matrix? For large matrices, the determinant can be calculated using a method called expansion by minors. This involves expanding the determinant along one of the rows or columns and using the determinants of smaller matrices to find the determinant of the original matrix. matrix-determinant-calculator. en WebThe determinant helps us find the inverse of a matrix, tells us things about the matrix that are useful in systems of linear equations, calculus and more.

Note that det (A)=∏ i=1:n λ i. So just setting λ 1 =M, λ n =1/M and λ i≠1,n =1 will give you det (A)=1. However, as M → ∞, cond (A) = M 2 → ∞ and λ n → 0, meaning your matrix is approaching singularity ...
