<h2>
Purpose
</h2>
Evaluate derivatives of network outputs with respect to weights.

<p><h2>
Synopsis
</h2>
<PRE>
g = mlpderiv(net, x)</PRE>


<p><h2>
Description
</h2>
<CODE>g = mlpderiv(net, x)</CODE> takes a network data structure <CODE>net</CODE>
and a matrix of input vectors <CODE>x</CODE> and returns a three-index matrix
<CODE>g</CODE> whose <CODE>i</CODE>, <CODE>j</CODE>, <CODE>k</CODE> element contains the
derivative of network output <CODE>k</CODE> with respect to weight or bias
parameter <CODE>j</CODE> for input pattern <CODE>i</CODE>. The ordering of the
weight and bias parameters is defined by <CODE>mlpunpak</CODE>.
