title: Element-wise multiplication in CVXPY
body: <p>I am trying to do element-wise multiplication in CVXPY in the objective function. Is this allowed as part of a convex problem? </p>
  
  <p><code>X</code> is a n x 1 variable.
  <code>V</code> is a n x n constant.</p>
  
  <p>I want to do the equivalent of <code>np.multiply(X, V*X)</code>, which returns an n x 1 vector. </p>
