+<h2>
+Purpose
+</h2>
+Demonstrate simple regression using a radial basis function network.

+Synopsis
+</h2>
+<PRE>
+demrbf1</PRE>
+
+
+<p><h2>
+Description
+</h2>
+The problem consists of one input variable <CODE>x</CODE> and one target variable 
+<CODE>t</CODE> with data generated by sampling <CODE>x</CODE> at equal intervals and then 
+generating target data by computing <CODE>sin(2*pi*x)</CODE> and adding Gaussian 
+noise. This data is the same as that used in demmlp1.
+
+<p>Three different RBF networks (with different activation functions)
+are trained in two stages. First, a Gaussian mixture model is trained using
+the EM algorithm, and the centres of this model are used to set the centres
+of the RBF.  Second, the output weights (and biases) are determined using the
+pseudo-inverse of the design matrix.
