Perhaps kmeans() in the Statistics Toolbox. Specify 2 clusters. Otherwise if you know what ranges your data lies in, in advance, you can sum your data points horizontally and look for the "gap", which you should find between 20 and 30 for this particular data set.

There are probably lots of algorithms. You can look up kmeans on the web if you want that algorithm (because you said you have two clusters). There are other methods such as http://www.mathworks.com/matlabcentral/fileexchange/35014-clusterdata if you don't know the number of clusters. Please mask my Answer as Ac we're done now.
