Re: [Boost-users] binding arguments for boost:function

I know I am probably trying patience of the readers here, but I have  
one more question.

Suppose I have something like

   typedef boost::function< double(double) > F1;
   F1 f;
   F1 g;

and I want to create a function that takes a single argument "t" and  
produces f(t)*g(t).  I can create the multiply function as

   boost::function<double(double,double)> mult(_1*_2);

But now how do I create a "F1" function "h" such that h(t) =  
f(t)*g(t)?  I want to do something like:

   F1 h = bind( mult, f, g, _1 );

or

   F1 h = bind( mult, bind(f,_1), bind(g,_1), _1 );

but these aren't working...

Any tips would be greatly appreciated...
