Try this:
% data = the variable name of your array
stdDev = std(data(:)) % Compute standard deviation
meanValue = mean(data(:)) % Compute mean
zFactor = 1.5; % or whatever you want.
% Create a binary map of where outliers live.
outliers = abs(data-meanValue) > (zFactor * stdDev);

I don't know how to define outliers in text (words). For example, in this comment that you're reading now, which of the words are "outliers" and why?
