I can’t find the include file to get index_norm_inf(A) to compile where A is a matrix? Either there is a typo in the documentation quoted below or I’m misunderstanding something fundamental like what type to send it? I’m using a regular vector and matrix for now.

norms

t = norm_inf(v); i = index_norm_inf(v);

t = norm_1(v);   t = norm_2(v);

t = norm_inf(A); i = index_norm_inf(A);

t = norm_1(A);   t = norm_frobenius(A);

We’re using Eclipse with Cygwin GnuC++ on Windows 7 (64-bit) along with Visual Studio 2012.

I’ve grepped the source code both hpp & cpp with no luck so far: find . -name '*.hpp' -print -exec grep -i index_norm_inf {} \;

Here’s what I’ve tried:

#include "boost/numeric/interval.hpp" // from range a to b inclusive

#include "boost/tuple/tuple.hpp" // heterogeneous container lists

#include "boost/tuple/tuple_comparison.hpp"

#include "boost/tuple/tuple_io.hpp"

#include "boost/numeric/ublas/matrix.hpp"

#include "boost/numeric/ublas/matrix_sparse.hpp"

#include "boost/numeric/ublas/matrix_expression.hpp"

#include "boost/numeric/ublas/matrix_proxy.hpp"

#include "boost/numeric/ublas/functional.hpp"

#include "boost/numeric/ublas/vector.hpp" // homogeneous

#include "boost/numeric/ublas/vector_sparse.hpp"

#include "boost/numeric/ublas/vector_expression.hpp"

#include "boost/numeric/ublas/vector_proxy.hpp"

#include "boost/numeric/ublas/io.hpp"

#include "boost/numeric/ublas/lu.hpp" // Lower Upper

#include "boost/numeric/ublas/matrix_proxy.hpp"

#include "boost/numeric/ublas/triangular.hpp"

#include "boost/numeric/ublas/traits.hpp"

#include "boost/numeric/ublas/symmetric.hpp"

#include "boost/math/tools/roots.hpp"

#include "boost/math/constants/constants.hpp"

#include <iostream>

Thanks! I see there is a new release to download, version 1.55.0 (11/11/2013)
