4549	vector/matrix_assign do not work for integral types	Marco Guazzone <marco.guazzone@…>	Gunter	"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."	Bugs	new	To Be Determined	uBLAS	Boost Development Trunk	Problem			jonathan.jones@…
