## VEC Reshape to a Vector

Section: Elementary Functions

### Usage

Reshapes an n-dimensional array into a column vector. The general syntax for its use is

       y = vec(x)

where `x` is an n-dimensional array (not necessarily numeric). This function is equivalent to the expression `y = x(:)`.

### Example

A simple example of the `vec` operator reshaping a 2D matrix:

    --> A = [1,2,4,3;2,3,4,5]

    A =

     1 2 4 3
     2 3 4 5

    --> vec(A)

    ans =

     1
     2
     2
     3
     4
     4
     3
     5
