title: Matlab undefined 'matrix' errors
body: <p>I need a hand with one matlab question it's been the bain of my thoughts for the past few days.</p>
  
  <p>Ok. I have to produce a matrix respective to the horizontal vector <code>T</code> and the vertical vector <code>V</code>.</p>
  
  <pre><code>T = [40:10:-40];
  V = [10:10:60]';
  </code></pre>
  
  <p>And implement the equation to fill the matrix/table </p>
  
  <p><code>q = 35.74 + 0.6215*T - 35.75*v^0.16 + 0.4275*T^0.16</code></p>
  
  <p>SO what I produced in matlab was </p>
  
  <pre><code>T = [40:10:-40];
  V = [10:10:60]';
  q = (35.74+(0.6215*T))-(35.75.*V.^0.16)+(0.4275.*T.*V.^0.16);
  
  matrix((T,V)*q)
  </code></pre>
  
  <p>component q throws errors such as <code>error using .*     matrix dimensions must agree</code></p>
  
  <p>and <code>undefined function 'matrix' for input arguments of type 'double'</code></p>
  
  <p>Would someone be able to throw me a lifeline here? 
  any help much appreciated</p>
  
  <p>Thanks</p>
