vector/matrix_assign do not work for integral types

[Marco Guazzone <marco.guazzone@…>]

I have found a possible problem in vector_assign and matrix_assign functions when vector and matrix values have integral type.

For instance, when you try to assign two integral vectors (e.g., ublas::vector<int>), you'll end up with the following runtime assertion:

Check failed in file
boost-trunk/boost/numeric/ublas/detail/vector_assign.hpp
at line 370:
detail::expression_type_check (v, cv)
terminate called after throwing an instance of
'boost::numeric::ublas::external_logic'
 what():  external logic or bad condition of inputs
Aborted (core dumped)

Similar exception will be thrown for integral matrices.

I have identified two possible issues:

1. In detail/vector_assign.hpp and detail/matrix_assign.hpp, the check in function detail::equals should use <= instead of <.

2. In detail/config.hpp, macro BOOST_UBLAS_TYPE_CHECK_MIN should get zero for integral types.

Possible solution.

Test case: test copy-construction/-assignement of an integral vector and an integral matrix. The test fails to run if the proposed patch is not applied.

It seems that this patch has been never added to the repo. I cannot see it in current svn trunk.

Since I've realized that one of the involved files is changed (i.e., boost/numeric/ublas/detail/config.hpp), I add a new patch to fit actual changes.

The test file that I've already attached is still OK.

Patch file changed to fit actual (Boost 1.51) changes.

When I ran the attached test case , it works for integral vector but not integral matrix for Boost 1.65.1 . Please let me know if we have fix for integral matrix ?

Thanks
