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). ...

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. ...
Another way of saying is to call M a {eq}2 \text{x} 3 {/eq} matrix, or to say that M has an order of {eq}2 \text{x} 3 {/eq}. The order or a matrix is the number of rows and columns that it has: if a matrix has m rows and n columns, the order of such matrix ...
Identity matrix (=MUNIT) Excel also enables the user to create the identity matrix of any order through the array formula MUNIT. Let us suppose we want an identity matrix of order (10⋅10), then what we need to do is to select the required range of 10 rows and 10 columns as in Fi...
