Why is it called an identity 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. ...
A matrix which has all the diagonal elements as ones and all the other element except diagonal element as zero is known as identity matrix. The order of a matrix can be represented as mxn where m is the number of rows in the matrix and n is the number of columns in the matrix....
