%
%   Usage:
%     exp_glasberg2002(flags)
%
%   The following flags can be specified;
%
%     'fig1'    Reproduce Fig. 1 of glasberg2002.
%
%     'fig1b'   Similar to fig1 but using 2006 revised data for middle ear
%               filter.
%
%     'fig5'    Reproduce Fig. 5 of glasberg2002.
%
%   Examples:
%   ---------
%   To display Fig.1 of Glasberg et al. (2002) use :
%
%     exp_glasberg2002('fig1');
