## Types of Matrices

Row Matrix A matrix is called a row matrix, if it has only one row. e.g., the matrix $M = \begin {bmatrix} 2 & -1 & 7 \\ \end{bmatrix}$ is a row matrix of order 1-by-3 and $N = \begin {bmatrix} 1 & -1 \\ \end{bmatrix}$ is a row matrix of order 1-by-2. Column Matrix A ...

Question 1. Find the order of the following matrices. Solution: $$A = \begin {bmatrix} 2 & 3 \\ -5 & 6 \\ \end{bmatrix}$$ Order of matrix A is 2-by-2   $$B = \begin {bmatrix} 2 & 0 \\ 3 & 5 \\ \end{bmatrix}$$ Order of matrix B is 2-by-2    C = \begin {bmatrix} 2 ...
