Row reduction and cofactor expansion
Webpage 1 . 2.1 Matrices. Defs. A matrix is a table of entries (usually numbers). It is denoted by a capital letter such as A. The plural of matrix is matrices. Rows run horizontal. WebTheorem 1 (Cofactor expansion) The determinants of nxn matrix A can be evaluated by multiplying every element along a certain row (or column) with the value of its cofactor and then adding up all the products; that is, for each 1 i n, 1 j n, Cofactor expansion along the i throw: 1 1 2 2 3 3 1. A ... n ij i j i i i i i i i n in j

WebThe process of computing the determinant given by Definition def:toprowexpansion is called the cofactor expansion along the first row. We will later show that we can expand along any row or column of a matrix and obtain the same value. This surprising result, known as the Laplace Expansion Theorem, will be the subject of DET-0050. Webthe same value as for the first-row expansion. b Determinant of an n 3 n matrix. Since we know how to evaluate 3 3 3 deter-minants, we can use a similar cofactor expansion for a 4 3 4 determinant. Choose any row or column and take the sum of the products of each entry with the corresponding cofactor. The determinant of a 4 3 4 matrix involves ...
