% One-dimensional fractional Brownian motion (fBm) generator
% given the Hurst parameter 'H' in [0,1], the output is 'W_vec' computed over a vector t_vec of 'n' equally spaced time points
%

% CNR-IASI BioMatLab (BML), National Research Council of Italy
%
% INPUT: Hurst parameter 'H' in [0,1], number of grid points 'n', final time 'T'.
% OUTPUT: Fractional Brownian motion 'W_vec' at times 't_vec'
% If no output is invoked, the function plots the fBm.
%
% Example: plot fBm with Hurst parameter 0.9 on the interval [0,5]
% [W_vec,t_vec]=fBm_BML(0.9,1000,5);
% figure
% plot(t_vec,W_vec)
