title: How to get vector from matrix in Maxima
body: <p>I want to multiply matrix M to vector V. Should be a vector.
  I write</p>
  
  <pre><code>M:matrix([a,b,c],[d,e,f],[g,h,r]);
  V:[w,k,t];
  res:M.V;
  </code></pre>
  
  <p>I get the column-matrix. 
  I want to get list <code>[a*w+c*t+b*k,d*w+f*t+e*k,g*w+r*t+h*k]</code>. 
  OK. I have to write <code>res:[res[1][1],res[2][1],res[3][1]];</code>
  How to do it more efficiently?</p>
