Web4.2. MATRIX NORMS 217 Before giving examples of matrix norms, we need to re-view some basic definitions about matrices. Given any matrix A =(a ij) ∈ M m,n(C), the conjugate A of A is the matrix such that A ij = a ij, 1 ≤ i ≤ m, 1 ≤ j ≤ n. The transpose of A is the n×m matrix A￿ such that A￿ ij = a ji, 1 ≤ i ≤ m, 1 ≤ j ≤ n. WebDefinition. The adjugate of A is the transpose of the cofactor matrix C of A, ⁡ =. In more detail, suppose R is a unital commutative ring and A is an n × n matrix with entries from R.The (i, j)-minor of A, denoted M ij, is the determinant of the (n − 1) × (n − 1) matrix that results from deleting row i and column j of A.The cofactor matrix of A is the n × n matrix … east coast white fish https://loudandflashy.com
