 Matrices Matrix A matrix is a rectangular table of elements (usually called entries), which may be numbers.. We are only going to work with matrices which entries are real numbers. The horizontal lines in a matrix are called rows and the vertical lines are called columns. A matrix with m rows and n columns is called an m-by-n matrix (written m × n) and m and n are called its dimensions. (Frecuently an m-by-n matrix is said to has an order of m × n ("order" = "size")). A 3x3 matrix can be: $A=\left(\begin{matrix}a_{11}&a_{12}&a_{13}\\a_{21}&a_{22}&a_{23}\\a_{31}&a_{32}&a_{33}nd{matrix}\right)$ While a general mxn matrix is: $A=\large\left(\begin{array}a_{11}&a_{12}&\cdots&a_{1m}\\a_{21}&a_{22}&\cdots&a_{2m}\\\vdots&\vdots&\ddots&\vdots\\a_{n1}&a_{n2}&\cdots&a_{nm}\end{array}\right)$ that can be written as: A = (aij ), where i=1,...,n and j=1,2,...,m Observe that almost always upper-case letters denote matrices, while the corresponding lower-case letters, with two subscript indices, represent the entries, for example, the (i,j)th entry of a matrix A is most commonly written as ai,j.
