Matrix Review Textbooks use boldface type to denote matrices and vectors. We will denote a matrix by underlining it (e.g., A ). For this course, we will work with 2- and 3- dimensional matrices. Multiplication : (multiply each row of A times the corresponding elements in each column of B ). If matrix A has m rows and n columns, and matrix B has n rows and p columns, then the product AB will have m rows and p columns. A and B must be commensurable: the product AB cannot be calculated unless the number of columns in A equals the number of rows in B . {} {} [] {} () () () () () ( ) () () () () () () () () ( ) () () () () () () () () ( ) () () () [] [] [] () () () () () () () () () [] [] [] 1 3 1 3 3 3 3 . 21 2 . 14 2 . 12 9 . 0 6 1 . 3 3 2 . 7 5 9 . 0 2 1 . 3 4 2 . 7 0 9 . 0 7 1 . 3 1 2 . 7 3 3 3 3 3 3 3 24 165 47 12 58 10 32 152 30 4 6 5 3 3 5 17 6 6 3 9 5 1 6 2 3 7 5 4 2 5 4 3 0 17 2 6 4 9 0 1 2 2 4 7 0 4 7 5 1 3 3 17 7 6 1 9 3 1 7 2 1 7 3 matrix 1 3 9 . 0 1
