.. cpp:class:: IntervalMesh

    *Parent class(es)*
    
        * :cpp:class:`Mesh`
        
    Interval mesh of the 1D line [a,b].  Given the number of cells
    (nx) in the axial direction, the total number of intervals will
    be nx and the total number of vertices will be (nx + 1).


    .. cpp:function:: IntervalMesh(std::size_t nx, double a, double b)
    
        Constructor
        
        *Arguments*
            nx (std::size_t)
                The number of cells.
            a (double)
                The minimum point (inclusive).
            b (double)
                The maximum point (inclusive).
        
        *Example*
            .. code-block:: c++
        
                // Create a mesh of 25 cells in the interval [-1,1]
                IntervalMesh mesh(25, -1.0, 1.0);
        


    .. cpp:function:: IntervalMesh(MPI_Comm comm, std::size_t nx, double a, double b)
    
        Constructor
        
        *Arguments*
            comm (MPI_Comm)
                MPI communicator
            nx (std::size_t)
                The number of cells.
            a (double)
                The minimum point (inclusive).
            b (double)
                The maximum point (inclusive).
        
        *Example*
            .. code-block:: c++
        
                // Create a mesh of 25 cells in the interval [-1,1]
                IntervalMesh mesh(MPI_COMM_WORLD, 25, -1.0, 1.0);
