Introduction to Vectors ... The matrix finds all the differences 1,3,5,7 at once. Important Note: Multiplication a row at a time. You may already have learned about multiplying Ax, a matrix times a vector. Probably it was explained differently, using the rows instead of the columns. The usual way takes the dot product of each row with x:

Multiplying any matrix M by a square matrix S on either side results in a matrix of the same size as M, provided that the sizes of the matrices are such that the multiplication is allowed. If S is the identity matrix I, then the result is the original matrix M: 88 Chapter 7: Introduction to Matrices Equation7.5: 2×2matrix multiplication ...

3.1 Basic matrix notation We recall that a matrix is a rectangular array or table of numbers. We call the individual numbers entriesof the matrix and refer to them by their row and column numbers. The rows are numbered 1;2;::: from the top and the columns are numbered 1;2;::: from left to right. So we use what you might think of as a (row, colum)

6. A square matrix A= [aij] is said to be an upper triangular matrix if aij = 0 for i>j. A square matrix A= [aij] is said to be an lower triangular matrix if aij = 0 for i<j. A square matrix Ais said to be triangular if it is an upper or a lower triangular matrix. For example 2 1 4 0 3 −1 0 0 −2 is an upper triangular matrix.

Suppose A is a square matrix. We look for an “inverse matrix” A−1 of the same size, such that A−1 times A equals I. Whatever A does, A−1 undoes. Their product is the identity matrix—which does nothing to a vector, so A−1Ax = x. But A−1 might not exist. What a matrix mostly does is to multiply a vector x. Multiplying Ax = b by A−1
