/** \brief main namespace of uBLAS.
*
* Use this namespace for all operations with uBLAS. It can also be abbreviated with
* \code namespace ublas = boost::numeric::ublas; \endcode
*
* A common practice is to bring this namespace into the current scope with
* \code using namespace boost::numeric::ublas; \endcode.
*
* However, be warned that using the ublas namespace and the std::vector at the same time can lead to the compiler to confusion.
* The solution is simply to prefix each ublas vector like \c boost::numeric::ublas::vector<T>. If you think it's too long to
* write, you can define a new namespace like \c namespace ublas = boost::numeric::ublas and then just declare your vectors
* with \c ublas::vector<T>. STL vectors will be declared as vector<T>. No need to prefix with \c std::

/** \brief A dense matrix of values of type \c T.
*
* For a \f$(m \times n)\f$-dimensional matrix and \f$ 0 \leq i < m, 0 \leq j < n\f$, every element \f$ m_{i,j} \f$ is mapped to
* the \f$(i.n + j)\f$-th element of the container for row major orientation or the \f$ (i + j.m) \f$-th element of
* the container for column major orientation. In a dense matrix all elements are represented in memory in a
* contiguous chunk of memory by definition.
*
* Orientation and storage can also be specified, otherwise a \c row_major and \c unbounded_array are used. It is \b not
* required by the storage to initialize elements of the matrix.
*
* \tparam T the type of object stored in the matrix (like double, float, complex, etc...)
* \tparam L the storage organization. It can be either \c row_major or \c column_major. Default is \c row_major
* \tparam A the type of Storage array. Default is \c unbounded_array

/** \brief A fixed size dense matrix of values of type \c T. Equivalent to a c-style 2 dimensional array.
*
* For a \f$(m \times n)\f$-dimensional fixed_matrix and \f$ 0 \leq i < m, 0 \leq j < n\f$, every element \f$ m_{i,j} \f$ is mapped to
* the \f$(i.n + j)\f$-th element of the container for row major orientation or the \f$ (i + j.m) \f$-th element of
* the container for column major orientation. In a dense matrix all elements are represented in memory in a
* contiguous chunk of memory by definition.
*
* Orientation and storage can also be specified, otherwise \c row_major and \c std::array are used. It is \b not
* required by the storage container to initialize elements of the matrix.
*
* \tparam T the type of object stored in the matrix (like double, float, std::complex<double>, etc...)
* \tparam L the storage organization. It can be either \c row_major or \c column_major. Default is \c row_major
* \tparam A the type of Storage array. Default is \c std::array<T, M*N>

/** \brief An array based matrix class which size is defined at type specification or object instanciation
*
* This matrix is directly based on a predefined C-style arry of data, thus providing the fastest
* implementation possible. The constraint is that dimensions of the matrix must be specified at
* the instanciation or the type specification.
*
* For instance, \code typedef c_matrix<double,4,4> my_4by4_matrix \endcode
* defines a 4 by 4 double-precision matrix. You can also instantiate it directly with
* \code c_matrix<int,8,5> my_fast_matrix \endcode. This will make a 8 by 5 integer matrix. The
* price to pay for this speed is that you cannot resize it to a size larger than the one defined
* in the template parameters. In the previous example, a size of 4 by 5 or 3 by 2 is acceptable,
* but a new size of 9 by 5 or even 10 by 10 will raise a bad_size() exception.
*
* \tparam T the type of object stored in the matrix (like double, float, complex, etc...)
* \tparam N the default maximum number of rows
* \tparam M the default maximum number of columns
