# Make a Column Vector in MATLAB

This tutorial will discuss creating a column vector using the semicolon symbol in MATLAB.

## Creating Column Vectors Using the Semicolon Symbol in MATLAB

A column vector is a vector that has only one column. To create a column vector in MATLAB, we must use the semicolon symbol after each element except the last element. For example, let’s create a column vector with three elements using the semicolon symbol. See the code below.

``````clc
v = [1;2;3]
``````

Output:

``````v =

1
2
3
``````

We can also take the transpose of a row vector to convert it into a column vector. For example, let’s create a row vector and convert it into a column vector using the `transpose()` function. See the code below.

``````clc
RowV = [1 2 3]
colV = transpose(RowV)
``````

Output:

``````RowV =

1     2     3

colV =

1
2
3
``````

We can also use the apostrophe symbol instead of the `transpose()` function to take the transpose of a vector or matrix. For example, we can change the third line of the above code to `RowV`, generating the same result. We can also convert a matrix into a column vector using the colon symbol. For example, let’s create a matrix and convert it into a column vector using the colon symbol. See the code below.

``````clc
RowV = [1 2 3; 7 8 9]
colV = RowV(:)
``````

Output:

``````RowV =

1     2     3
7     8     9

colV =

1
7
2
8
3
9
``````

In the output, the columns of the given matrix are placed vertically on top of each other to create a single column vector. The first column will be on top, and the second column will be below the first column, and so on.
