Here you will learn what is column matrix definition and order of column matrix with examples.
Let’s begin –
Column Matrix
Definition : A matrix having only one column is called a column matrix or a column vector.
It is matrix having all its elements in a single column. It has one column and multiple rows.
The order of column matrix is \(n \times 1\).
The General form of column matrix is \(\begin{bmatrix}a_{11} \\ a_{12} \\ .\\ .\\ . \\ a_{1n}\end{bmatrix}\)

Examples :
1). \(\begin{bmatrix} 1 \\ 2 \\ -1 \end{bmatrix}\) is a column matrix.
The order of the above matrix is \(3 \times 1\).
2). \(\begin{bmatrix} 3 \\ 5 \end{bmatrix}\) is a column matrix.
The order of above matrix is \(2 \times 1\).
3). \(\begin{bmatrix} 1 \end{bmatrix}\)is a column matrix.
The order of above matrix is \(1 \times 1\).
4). \(\begin{bmatrix} 1 \\ 2 \\ -1 \\ 4 \end{bmatrix}\) is a column matrix.
The order of above matrix is \(4 \times 1\).
5). \(\begin{bmatrix} 1 \\ 2 \\ 3 \\ 4 \\ 5 \end{bmatrix}\) is a column matrix.
The order of above matrix is \(5 \times 1\).
