Hi Robert,

Yep, the following works great. Not sure why the same code doesn't
work when I have it in my larger project, but I guess that's for me to
figure out.

There is still the problem with the std::for_each, see below:

#include <iostream>

#include <vector>
#include <algorithm>
#include <math.h>
#include "boost/bind.hpp"

#include <boost/numeric/ublas/vector.hpp>
#include <boost/numeric/ublas/io.hpp>

int main( )
{
 boost::numeric::ublas::vector<double> v(10);
 double exponent = 2.1;
 std::fill(v.begin(), v.end(), 8.0);
 // The following works just fine:

 std::transform( v.begin(), v.end(), v.begin(), boost::bind( pow, _1,
exponent ) );

 // But the for_each doesn't apply the power function, just leaves
the vector unaltered
 std::for_each( v.begin(), v.end(), boost::bind( pow, _1, exponent ) );
 // Print the result
 std::cout<< v << std::endl;

 return 0;
}

Compiled with: g++ -O2 -Wfatal-errors -Wall -g -ansi
-I/usr/local/boost/include -o main main.cpp
