In this calculator skill lesson, you will learn how to generate an identity matrix on your graphing calculator, and how to use it in various calculations. The identity matrix is a square matrix with ones on the diagonal and zeros everywhere else. By multiplying a matrix by the identity matrix, you will get the same matrix back, as long as the identity matrix is the same dimension. This is a useful tool in Input/Output analysis and other mathematical calculations.
