\section{VEC Reshape to a Vector}

\subsection{Usage}

Reshapes an n-dimensional array into a column vector.  The general
syntax for its use is
\begin{verbatim}
   y = vec(x)
\end{verbatim}
where \verb|x| is an n-dimensional array (not necessarily numeric).  This
function is equivalent to the expression \verb|y = x(:)|.
\subsection{Example}

A simple example of the \verb|vec| operator reshaping a 2D matrix:
\begin{verbatim}
--> A = [1,2,4,3;2,3,4,5]
A = 
  <int32>  - size: [2 4]
 
Columns 1 to 4
 1  2  4  3  
 2  3  4  5  
--> vec(A)
ans = 
  <int32>  - size: [8 1]
 
Columns 1 to 1
 1  
 2  
 2  
 3  
 4  
 4  
 3  
 5  

\end{verbatim}
