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
