data_li2020 - - Load experimental results from Li et al. (2020)

Usage

data = data_li2020(dataFlag,measure)
data = data_li2020(fig)

Description

DATA_LI2020 provides individually measured/modified HRTFs/BRIRs and experimental results from Li et al. (2020). Use the fig flag to obtain data shown in figures from Li et al. (2020).

The dataFlag flag may be used to choose between HRTFs and various experimental results:

`'hrtf'`	HRTFs used in all experiments.
`'exp1'`	Experimental results of Exp. A. Default.
`'exp2'`	Experimental results of Exp. B.
`'exp3'`	Experimental results of Exp. C.
`'exp4'`	Experimental results of Exp. D.
`'exp5'`	Experimental results of Exp. E.

Additional flags may be:

`'plot'`	Plot results as published.
`'no_plot'`	No plots. Default.
