i'm new to boost, but use the standard template library a lot. I have 
problems with the following code. 

line 12: according to the reference, i should be able to do this, but cannot compile. compile error is very long, tell me if I should include them here.

my compiler: gcc version 4.0.1 (Apple Inc. build 5490) 

thanks in advance for your help. 

  1 #include <boost/multi_array.hpp>
  2 
  3 int main ( ) {
  4 
  5   typedef boost::multi_array<double,2> matrix_type;
  6   typedef matrix_type::iterator        iterator;
  7 
  8   matrix_type mat(boost::extents[2][3]);
  9   double v = .2;
 10 
 11   for(iterator it=mat.begin();it!=mat.end();++it) {
 12     (*it) = v; // compile error
 13   }
 14 }
