I look forward to your notification that this has been done :)  Thanks!

OK, here is the code:

#include<boost/numeric/ublas/storage.hpp>
#include<boost/numeric/ublas/lu.hpp>

using namespace boost::numeric::ublas;

int main(){

  // create a permutation matrix
  permutation_matrix P( 5 );
  // default contructions gives the identity-permutation

  return 0;
}

The errors are:
g++ -c -I. -I/s/chopin/a/grad/dane/thesis/code/boost-1.32/include/boost-1_32   
-Wall -g3 -o permutationTest.o permutationTest.cpp
In file included from permutationTest.cpp:5:

permutationTest.cpp: In function `int main()':

   function)
permutationTest.cpp:15: error: (Each undeclared identifier is reported only 
   once for each function it appears in.)
permutationTest.cpp:15: error: parse error before `(' token

I thought that this error might signal the need for including vector.hpp (or 
vector_expression.hpp or something) but this did not fix it.  Including 
operation.hpp (which I beleive contains the definition for axpy) causes 
several screen-fulls of errors!

Again, I am at a loss and appreciate any help I might receive.

Thank you,
