+Description
+</h2>
+The data is
+drawn from three spherical Gaussian distributions with priors 0.3,
+0.5 and 0.2; centres (2, 3.5), (0, 0) and (0,2); and standard deviations
+0.2, 0.5 and 1.0.  <CODE>data = dem2ddat(ndata)</CODE> generates <CODE>ndata</CODE>
+points.  
+
+<p><CODE>[data, c] = dem2ddat(ndata)</CODE> also returns a matrix containing the
+centres of the Gaussian distributions.
