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. + +<p><h2> +See Also +</h2> +<CODE><a href="gauss.htm">gauss</a></CODE>, <CODE><a href="gsamp.htm">gsamp</a></CODE>, <CODE><a href="histp.htm">histp</a></CODE><hr> +<b>Pages:</b> +<a href="index.htm">Index</a> +<hr> +<p>Copyright (c) Ian T Nabney (1996-9) + + +</body> +</html> \ No newline at end of file
