This text deals with matrix algebra, as opposed to linear algebra. Without arguing semantics, I view matrix algebra as a subset of linear algebra, focused primarily on basic concepts and solution techniques. There is little formal development of theory and abstract concepts are avoided A matrix is a rectangular array of numbers. An m by n matrix is a matrix with m rows and n columns: Each entry aij in the matrix is a number, where i tells what row the number is on, and j tells which column it is in.

known as matrices, the key concepts and the wide applicability of linear algebra are easily missed. So we reiterate, Linear algebra is the study of vectors and linear functions. In broad terms, vectors are things you can add and linear functions are functions of vectors that respect vector addition. 1.2 What are Vectors This is a book on linear algebra and matrix theory. While it is self contained, it will work best for those who have already had some exposure to linear algebra. It is also assumed that the reader has had calculus.

The composition of matrix transformations corresponds to a notion of multiplying two matrices together. We also discuss addition and scalar multiplication of transformations and of matrices. 3.5: Matrix Inverses In this section, we learn to divide by a matrix. This allows us to solve the matrix equation Ax=b in an elegant way 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.
