+Description
+</h2>
+
+<CODE>e = mdnerr(net, x, t)</CODE> takes a mixture density network data
+structure <CODE>net</CODE>, a matrix <CODE>x</CODE> of input vectors and a matrix
+<CODE>t</CODE> of target vectors, and evaluates the error function
+<CODE>e</CODE>. The error function is the negative log likelihood of the
+target data under the conditional density given by the mixture model
+parameterised by the MLP.  Each row of <CODE>x</CODE> corresponds to one
+input vector and each row of <CODE>t</CODE> corresponds to one target vector.
