File name : 'HF5.m'. This file can be used
for calculating the retention time of a certain molecule
in hollow-fiber flow-field flow fractionation (HF5)

Four input values : 'Rf', 'D', 'F_in', 'F_out'
One ouput value : 't_r'
Rf: Retention factor
D: Diffusion coefficient of molecule (1e-9 m2/s)
F_in: Flow rate inlet (mL/min)
F_out: Flow rate outlet (mL/min)
t_r: Retention time (min)

Input syntax : HF5(Rf,D,F_in,F_out)
