bbmultq  Quick evaluation of BB*X.
   bbmultq(BB,X) computes the product BB*X quickly, in the sense that
   it assumes any relevant checks have been completed in advance.

   bbmultq is intended for evaluating matrix-matrix products inside a
   combining black-box routine. It should not be used for ordinary use.
   Please use bbmult for normal evaluation.

   bbmultq supports matrix-matrix products. If necessary, the product
   is evalated as a series of matrix-vector products.
