An identity matrix is always an square matrix: As seen in equations 1 and 2, the order of an identity matrix is always n, which refers to the dimensions nxn (meaning there is always the same amount of rows and columns in the matrix). ...
It is called an identity matrix as it fulfills the same purpose as the number 1 in multiplication: to be a mathematical element that when multiplied with a matrix of compatible order, it returns the same matrix. What are the properties of an identity matrix? Identity matrices are diagonal, ...
