When interacting with the REST API, this is the HTTP body. An identity matrix is a square matrix in which all the elements of principal diagonals are one, and all other elements are zeros. It is denoted by the notation “I n” or simply “I”. If any matrix is multiplied with the identity matrix, the result will be given matrix. The elements of the given matrix remain unchanged. In other words, if all the main diagonal of a square matrix are 1’s and rest all o’s, it is called an identity matrix. Here, the 2 × 2 and 3 × 3 identity matrix is given below:
