+Description
+</h2>
+
+<p><CODE>demgauss</CODE> provides a simple illustration of the generation of
+data from Gaussian distributions. It first samples from a
+one-dimensional distribution using <CODE>randn</CODE>, and then plots a
+normalized histogram estimate of the distribution using <CODE>histp</CODE>
+together with the true density calculated using <CODE>gauss</CODE>.
+
+<p><CODE>demgauss</CODE> then demonstrates sampling from a Gaussian distribution
+in two dimensions. It creates a mean vector and a covariance matrix,
+and then plots contours of constant density using the function
+<CODE>gauss</CODE>. A sample of points drawn from this distribution, obtained
+using the function <CODE>gsamp</CODE>, is then superimposed on the contours.
