If a matrix stretches things out, then its determinant is greater than 1 1. If a matrix doesn't stretch things out or squeeze them in, then its determinant is exactly 1 1. An example of this is a rotation. If a matrix squeezes things in, then its determinant is less than 1 1.

WebThe determinant of a tridiagonal matrix A of order n can be computed from a three-term recurrence relation. Write f 1 = a 1 = a 1 (i.e., f 1 is the determinant of the 1 by 1 matrix consisting only of a 1), and let = . The sequence (f i) is called the continuant and satisfies the recurrence relation = with initial values f 0 = 1 and f −1 = 0. The cost of computing the … WebThis definition of an eigenvalue, which does not directly involve the corresponding eigenvector, is the characteristic equation or characteristic polynomial of A.
