========= Variables ========= The LINEAR2D model exposes a single variable via :class:`macrostat.models.LINEAR2D.VariablesLINEAR2D`: - ``State`` – the 2D state vector :math:`x_t` recorded at each timestep. Internally this is stored as a tensor of shape ``(timesteps, 2)``. .. csv-table:: :file: variables.csv :header-rows: 1
