title: Dimension of arrays do not agree
body: <p>I have to solve this matrix equation in MATLAB</p>
  
  <p>(A + p(1)<em>E)</em> V(1) = B , <strong>and find V(1)</strong></p>
  
  <p><strong>B</strong> dimension is <em>280 x 4</em><br>
  <strong>A</strong> dimension is <em>280 x 280</em><br>
  <strong>E</strong> dimension is <em>280 x 280</em><br>
  <strong>p</strong> dimension is <em>15 x 1</em>   </p>
  
  <p>I have tried this</p>
  
  <pre><code>L=inv((A + p(1)*E));      
  V(1) = B*L;
  </code></pre>
  
  <p>but i get this <strong>error</strong> </p>
  
  <pre><code>Error using ==&gt; mtimes
  Inner matrix dimensions must agree. 
  </code></pre>
  
  <p>Do you know what goes wrong, or an other way to solve it?  </p>
  
  <p><em>Thanks in advance</em></p>
