# Turn an Array into a Column Vector in MATLAB

** Conversion of an Array into a Column Vector. This conversion can be done using a(:) operation. A(:) reshapes all elements of A into a single column vector. This has no effect if A is already a column vector.**

**Example 1 **

## Matlab

`% MATLAB code for Conversion of an array ` `% into a column vector` `a = [2 4 6 8] ` `% Initializing an array of some elements` ` ` `% Converting above array into a column ` `% vector using a(:) operation` `Column_Vector = a(:)` |

**Output:**

**Example 2**

## Matlab

`% MATLAB code for Conversion of an ` `% array matrix into a column vector.` `a = [1 2; 3 4; 5 6] ` `% Initializing an array` ` ` `% Converting above array matrix into a column ` `% vector matrix using a(:) operation` `Column_Vector_matrix = a(:)` |

**Output:**
