Class 12 Maths - Types Of Matrices
(1) Row matrix
If in a matrix, there is only one row, then it is called a Row Matrix.
Thus $ A[a_{ij}]_{m \times n} $ is a row matrix if m = 1
e.g. [1 3 6] is a row matrix of order 1 × 3
(2) Column Matrix
A matrix which contains only one column, is called a column matrix. Thus $A[a_{ij}]_{m \times n}$ is a column matrix if n = 1.
e.g. $\begin{bmatrix} 5\\6 \\9 \end{bmatrix}$
(3) Square matrix
If number of rows and number of column in a matrix are equal, then it is called a square matrix. Thus $A[a_{ij}]_{m \times n}$ is a square matrix if m = n.
e.g. $\begin{bmatrix} 5 &6 \\7 & 8 \end{bmatrix}$
