title: Apply Singular Value Decomposition on input image
body: <p>I want to apply SVD to an input image and do a feature extraction. This is my code snippet:</p>
  
  <pre><code>[row, col] = size (A);
  for i = 1 : row
      for j = 1 : col
          [U,S,V] = svd(A(i,j));
      end
  end
  </code></pre>
  
  <p>Here <code>A</code> is the input image whose row = <code>347275</code> and col = <code>64</code>. After executing the code I get <code>U = 1</code>, <code>V = 1</code> and <code>S = 1.4981</code>. I know there is some mistake in my code. Can anyone suggest the right thing?</p>
