+<h2>
+Purpose
+</h2>
+Combines weights and biases into one weights vector.

+<PRE>
+w = mlppak(net)

+<p><h2>
+Description
+</h2>
+<CODE>w = mlppak(net)</CODE> takes a network data structure <CODE>net</CODE> and
+combines the component weight matrices bias vectors into a single row
+vector <CODE>w</CODE>. The facility to switch between these two
+representations for the network parameters is useful, for example, in
+training a network by error function minimization, since a single
+vector of parameters can be handled by general-purpose optimization
+routines.
+
+<p>The ordering of the paramters in <CODE>w</CODE> is defined by
+<PRE>
+
+  w = [net.w1(:)', net.b1, net.w2(:)', net.b2];
+</PRE>
+
+where <CODE>w1</CODE> is the first-layer weight matrix, <CODE>b1</CODE> is the
+first-layer bias vector, <CODE>w2</CODE> is the second-layer weight matrix,
+and <CODE>b2</CODE> is the second-layer bias vector.
