This function is not yet fully documented. This is a transcript of the text-formatted help.

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

   bbmultqh is intended for evaluating matrix-matrix products inside a
   combining black-box routine. It is not recommended for normal use;
   please use bbmult instead.

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