it can have any number of rows and columns. Identity matrix can be of any dimension i.e. The most important property of the identity matrix is, if a normal matrix is multiplied with the identity matrix then the resultant will always be the original matrix. In Matlab, the identity matrix is used for several purposes. There are different operations that can be performed with identity matrix-like multiplication, addition, subtraction, etc. It is also known as the elementary matrix or unit matrix.

Identity Matrix is defined as the matrix where all the diagonal elements are ones and the rest of the elements are zeroes. There are different types of matrices, one of them is Identity Matrix. If a matrix has 3 rows and 5 columns, then it is called a 3*5 matrix. They can be accessed with the help of row number and column number. Matrix is defined as the arrangement of the numbers in rows and columns. Introduction to Identity Matrix in Matlab
