Cofactor Expansion
DetMijis called the minor of. I teach how to use cofactor expansion to find the determinant of matrices. 3rd Order Determinant Laplace S Expansion This method is described as follows. . Most ecient way to calculate determinants is the cofactor expansion. One method for computing the determinant is called. Denote by Mij the submatrix of A obtained by. The determinant summarizes how much a linear transformation from a vector spaceto itself stretches its input. In this section we give a recursive formula for the determinant of a matrix called a cofactor expansion. Pick any i in 1ldots n. The formula is recursive in that we will compute the determinant of an n n matrix. 152 Let A aijbe an n n matrix. The formula is recursive in that we will compute the determinant of an n n matrix.
