title: Convert a cell containing matrices to a 2d matrix
body: <p>I want to find easy way to convert a 1x324 cell array which contains matrices to a 2-dimensional matrix. </p>
  
  <p>Each of the cell array's elements is a matrix of size 27x94, so they contain 2538 different values. I want to convert this cell array of matrices to a 324x2538 matrix - where the rows of the output contain each matrix (as a row vector) from the cell array.</p>
  
  <hr>
  
  <p>To clarify what my data looks like and what I'm trying to create, see this example:</p>
  
  <pre><code>matrix1 = [1,2,3,4,...,94 ; 95,96,97,... ; 2445,2446,2447,...,2538]; % (27x94 matrix)
  % ... other matrices are similar
  A = {matrix1, matrix2, matrix3, ..., matrix324}; % Matrices are in 1st row of cell array
  </code></pre>
  
  <p>What I am trying to get:</p>
  
  <pre><code>% 324x2538 output matrix
  B = [1     , 2   ,   ..., 2538  ;  % matrix1
       2539  , 2540,   ..., 5076  ;  % matrix2
       ...   
       819775, 819776, ..., 822312]; 
  </code></pre>
