I followed the UBLAS extensions here: http://www.crystalclearsoftware.com/cgi-bin/boost_wiki/wiki.pl?Examples_-_Ho... and I figured out how to extend functions like "exp" and "log" to act on a vector. But, those are functions of one argument. What I want is to be able to apply a function with one fixed argument, like std::pow, to a vector for some exponent exp, so I would like the code to look like: vector<double> v( 100 ); double exponent = 2.1; // some exponent value // ... fill v ... std::cout << apply_to_all( v, functor::my_pow<double>(exponent) ) << std::endl; std::cout << apply_to_all<functor::my_pow<double>(exponent) >( v ) << std::endl; OR std::cout << apply_to_all( v, functor::my_pow<double>() , exponent) << std::endl; How can I do this? I tried overloading apply_to_all and writing constructor code, but it didn't work because the return type of the apply function is static. P.S. I tried posting this to ublas lists, but got a message saying that my e-mail address is not registered. I guess that list is only for developers. Thanks, Max
