bbfunc  Get functions for computing matrix-vector products
   [f,fH,arg]=bbfunc(BB) returns functions handles for computing
   the matrix-vector products A*x and A'*x, where A corresponds to
   the black-box matrix BB.

   Use feval to evaluate a product:
     y=feval(f,x,arg{:})   computes y=A*x
     x=feval(fH,y,arg{:})  computes x=A'*y

   Use bbfuncm if you need to evaluate matrix-matrix products.
