In general, don't put too much faith in unsupervised clustering to directly train a classifier.
However, unsupervised clustering can be a useful tool for initializing a supervised clustering classifier. A competing method of initialization is to use individual unsupervised clustering for each class.
Most of all, the visualization of clustering results are very helpful for understanding classifier performance.

You might try Brett Shoelson's (of the Mathworks) app: http://www.mathworks.com/matlabcentral/fileexchange/35014-clusterdata
