 Hello and welcome to the session. In this session we are going to discuss the following question and the question says that, classify the following matrices. First part, A is equal to the matrix containing elements 5 minus 1, 2, 3, 0, minus 6. Second part, B is the matrix with elements 1, 5, 3. Third part, C is the matrix with elements 2, 3, 1 and 5. Fourth part, D is the matrix with elements minus 13, 4 and 2. Fifth part, E is the matrix with elements 1, 0, 0, 0, 2, 0, 0, 0, 3. Now the first part is A is equal to matrix 5 minus 1, 2, 3, 0, minus 6. This is a rectangular matrix, number of rows is equal to 3, number of columns is equal to 2. So, number of rows is not equal to the number of columns. Therefore, this is a rectangular matrix. Now the second part is B is equal to the matrix 1, 5, 3. This is a row matrix, B has exactly one row. The third part is C is equal to 2, 3, 1, 5, which is a square matrix. The number of rows is equal to the number of columns is equal to 2. The fourth part is D is equal to minus 13, 4, 2. This is a column matrix. D has one column. Fifth part is E is equal to 1, 0, 0, 0, 2, 0, 0, 0, 3. This is a diagonal matrix. The diagonal elements are non-zero. All the other elements except the diagonal elements are zero. This completes our session. Hope you enjoyed the session.
