Asquare matrixis a particular case of matrix that has the same number of rows as of columns and are therefore of an order {eq}n \text{x} n {/eq}. For example, $$\begin{pmatrix} 1 & 2 \\ 2 & 5 \end{pmatrix} , \begin{pmatrix} 8 & 2 \\ 2 & 8 \end{pmatrix} , \be...
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....
If In is the identity matrix of order n then (In)^(-1)= 02:10 Consider the identity function IN : N->N defined as, IN(x)=x for al... 04:48 If In is the identity matrix of order n then (In)^-1 (A) does not exis... 02:57 Let A be an orthogonal non-singular matrix...
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 Fig. 3.1-5. The array fo...
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). ...

In order to multiply two matrices A· B = C, the number of columns in A must equal the number of rows in B. This is necessary, so when computing the dot product, the vector lengths will be equal. If A is an [N × M] matrix, then B must be an [M × P] matrix to perform...
