Every identity matrix is a scalar matrix
WebAn example of a column matrix is: A = [ − 1 2 − 4 5] . is column matrix of order 4 x 1. Just like the row matrices had only one row, column matrices have only one column. Thus, the value of for a column matrix will be 1. Hence, the order is m × 1. The general form of a column matrix is given by A = [aij]m×1. Web7. Unit or identity matrix: A scalar matrix having diagonal elements as unity is known as unit matrix or an identity matrix. Example: 1 0 0 0 1 0 0 0 1. 8. Upper triangular matrix: A square matrix in which every element below the diagonal is zero is known as upper triangular matrix. Example: A = 4-2 5 0 0 3 0 0 2
