A MATLAB tool for analysis of Transient Otoacoustic Emission signals

function s = sget4(S, n, B)

%   sget4    picks the nth element s from list S.

%   s = sget4(S, n, B)
%
%   in: S   string list. String; elements separated by separators.
%   n   element to get (default 1)
%   B   separator character (default setstr(124))
%
%  out: s   n:th word from list
