comb-model:  A package to simulate Fractional Brownian walks on a comb-like structure.
==========================================================================================

This package simulate trajectories of the comb model via Langevin equations driven by fractional Gaussian noises (long-range correlated).

.. code-block:: python

    # Fractional Brownian walks on a plane
    
    import matplotlib.pyplot as plt
    from combmodel import langevin_fbn
    
    x,y=langevin_fbn(x0=0,y0=0,betax=1,betay=1,hurstx=0.5,hursty=0.5,tmax=1000,disable_tqdm=True)

    
    f, ax = plt.subplots(nrows=1, ncols=1, figsize=(9.1,7))
    ax.plot(x,y,color='#D62728',markersize=0,linewidth=2)
    ax.set_xlabel(r'Position, $x(t)$')
    ax.set_ylabel(r'Position, $y(t)$')
