Discriminant analysis method to classify data

my aim is to classify the data into two sections- upper and lower- finding the mid line of the peaks.

I would like to apply machine learning methods- i.e. Discriminant analysis.

Could you let me know how to do that in MATLAB?

It seems that what you are looking for is GMM (gaussian mixture model). With K=2 (number of mixtures) and dimension equal 1 this will be simple, fast method, which will give you a direct solution. Given components it is easy to analytically find a local minima (which is just a weighted average of means, with weights proportional to the std's).
