+<p><h2>
+Description
+</h2>
+<CODE>e = gperr(net, x, t)</CODE> takes a Gaussian Process data structure <CODE>net</CODE> together 
+with 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>. Each row
+of <CODE>x</CODE> corresponds to one input vector and each row of <CODE>t</CODE>
+corresponds to one target vector.
+
+<p><CODE>[e, edata, eprior] = gperr(net, x, t)</CODE> additionally returns the
+data and hyperprior components of the error, assuming a Gaussian
+prior on the weights with mean and variance parameters <CODE>prmean</CODE> and
+<CODE>prvariance</CODE> taken from the network data structure <CODE>net</CODE>.
