outlier

% Find value with largest difference from the mean
% 
% Description:
% 
%      Finds value with largest difference between it and sample mean,
%      which can be an outlier.
% 
% Usage:
% 
%      [out] = outlier(x,opposite,logical) 
% 
% Arguments:
% 
%        x: a data sample, vector in most cases. If argument is a
%          matrix, each column is treated as independent dataset. 
% 
% opposite: if set to 1 (default 0), gives opposite value (if largest value has
%           maximum difference from the mean, it gives smallest and vice
%           versa)
% 
%  logical: if set to 1 (default 0), gives vector of logical values, and possible
%           outlier position is marked by 1, others are 0
% 
% Value:
% 
%      A vector of value(s) with largest difference from the mean.
