StaticMatrix

.. cpp:namespace:: libsemigroups::StaticMatrix<PlusOp, ProdOp, ZeroOp, OneOp, Scalar>

This page contains information about the constructors for the :cpp:any:`StaticMatrix` class.

Default constructors

.. cpp:function:: StaticMatrix() = default

   Default constructor.

.. cpp:function:: StaticMatrix(StaticMatrix const&) = default

   Default copy constructor.

.. cpp:function:: StaticMatrix(StaticMatrix&&) = default

   Default move constructor.

.. cpp:function:: StaticMatrix& operator=(StaticMatrix const&) = default

   Default copy assignment operator.

.. cpp:function:: StaticMatrix& operator=(StaticMatrix&&) = default

   Default move assignment operator.

Matrix constructors

.. cpp:function:: StaticMatrix( \
        std::initializer_list<std::initializer_list<scalar_type>> m)

   Construct a matrix.

   :param m: the values to be copied into the matrix.

   :exceptions:
     this function guarantees not to throw a :cpp:any:`LibsemigroupsException`.

   :complexity:
     :math:`O(mn)` where :math:`m` is the template parameter :code:`R` and
     :math:`n` is the template parameter :code:`C`.

   **Example**

   .. code-block:: cpp

      Mat m({{1, 1}, {0, 0}});

.. cpp:function:: StaticMatrix( \
        std::vector<std::vector<scalar_type>> const& m)

   Construct a matrix.

   :param m: the values to be copied into the matrix.

   :exceptions:
     this function guarantees not to throw a :cpp:any:`LibsemigroupsException`.

   :complexity:
     :math:`O(mn)` where :math:`m` is the template parameter :code:`R` and
     :math:`n` is the template parameter :code:`C`.

Row constructors

.. cpp:function:: StaticMatrix(std::initializer_list<scalar_type> c)

   Construct a row.

   :param c: the values to be copied into the row.

   :exceptions:
     this function guarantees not to throw a :cpp:any:`LibsemigroupsException`.

   :complexity:
     :math:`O(n)` where :math:`n` is the size of the row being
     constructed.

   .. warning::

     This constructor only works for rows, i.e. when the template parameter
     :code:`R` is :code:`1`.

.. cpp:function:: StaticMatrix(RowView const& rv)

   Construct a row from a row view.

   :param rv: the row view.

   :exceptions:
     this function guarantees not to throw a :cpp:any:`LibsemigroupsException`.

   :complexity:
     :math:`O(n)` where :math:`n` is the size of the row being
     constructed.

   .. warning::

     This constructor only works for rows, i.e. when the template parameter
     :code:`R` is :code:`1`.
