WebAug 1, 2024 · A tridiagonal matrix has a nice form for the determinant. If the diagonal is a 1, a 2, …, above diagonal b 1, b 2, … and below diagonal is c 1, c 2, …, then the … WebComputing the determinant of a matrix A can be tedious. For example, if A is a 4×4 matrix, the cofactor expansion along any row or column involves calculating four cofactors, each of which involves the determinant of a 3×3 matrix. And if A is 5×5, the expansion involves five determinants of 4×4 matrices!

For example, the matrix " 6 7 2 11 # has the eigenvalue 13 and because the sum of the eigenvalues is 18 a second eigenvalue 5. A matrix with nonnegative entries for which the sum of the columns entries add up to 1 is called a Markov matrix. Markov Matrices have an eigenvalue 1. Proof.
WebDec 30, 2015 · A non-sparse n x n matrix has a determinant involving n! terms of length n so unless there are entries that are 0, the memory requirements would be in excess of n * (n!) . If your matrix is not marked as sparse then all n! of those calculations might actually be done (though the position of the 0s might matter in the efficiency.)
