Hi,

since there doesn't seem to be any address to send bugs to, I send the
following bug to the list.
I am using uBlas as in Boost 1_34_1, wich seems to be the latest
officical release. Unfortunately, I does not have access to the CVS.

In my view, in matrix_proxy.hpp, lines 4110 to 4115, contain a bug. In
my view, the following lines
 
    template<class M>
    BOOST_UBLAS_INLINE
    matrix_slice<const M> subslice (const M &data, typename M::size_type
start1, typename M::difference_type stride1, typename M::size_type
size1, typename M::size_type start2, typename M::difference_type
stride2, typename M::size_type size2) {
        typedef basic_slice<typename M::size_type, typename
M::difference_type> slice_type;
        return matrix_slice<const M> (data (), slice_type (start1,
stride1, size1), slice_type (start2, stride2, size2));
    }

Should be replaced by

    template<class M>
    BOOST_UBLAS_INLINE
    matrix_slice<const M> subslice (const M &data, typename M::size_type
start1, typename M::difference_type stride1, typename M::size_type
size1, typename M::size_type start2, typename M::difference_type
stride2, typename M::size_type size2) {
        typedef basic_slice<typename M::size_type, typename
M::difference_type> slice_type;
        return matrix_slice<const M> (data, slice_type (start1, stride1,
size1), slice_type (start2, stride2, size2));
    }

(i.e., the "()" after data in the declaration should be removed, in
consistency with similar definitions.)

Is there anybody out there who could confirm that this is a bug, and
could fix it for the next official release (if not done so already;
since the email archive is not searchable, I could not check if this
problem is already well known)?

Regards,

Mark

PS.: I apologise for the previous post, my email client was
unfortunately ill-configured.
