How about:

length(longwords)-length(unique(longwords))

You could use the unique command http://www.mathworks.com/help/techdoc/ref/unique.html

longwords={'banana';'milk';'butter';'cake';'lamb';'milk'}
uniqueWords=numel(unique(longwords))
unique(longwords)
repeatedWords=numel(longwords)-numel(unique(longwords))

Hope this helps..
