GAUSS_DD Gaussian data description.
 
       W = GAUSS_DD(A,FRACREJ,R)
 
 Fit a Gaussian density on dataset A. If requested, the r can be
 given to add some regularization to the estimated covariance matrix:
 sig_new = (1-r)*sig + r*eye(dim). Default r = 0.01!!! (might be
 dangerous!)

This version actually computes just the Mahalanobis distance to the mean. This should avoid underflows at the computation of a real Gaussian density (especially problematic in high dimensional spaces).
