Section 2.3 "Special Matrices", Powers & Non-Properties Definition of the Identity Matrix-- The identity matrix is a square matrix where the entries in the main diagonal are 1's and all other entries are 0's. Notation: I nis the n X n identity matrix. Examples 10 I2= 01 100 I3 =010 001 00 0100 I4= 10 01 Property of the Identity Matrix: If A is an m X n matrix then Im A = A A In= A Example
