+<p><h2>
+Description
+</h2>
+<CODE>g = glmgrad(net, x, t)</CODE> takes a generalized linear model
+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 gradient <CODE>g</CODE> of the error
+function with respect to the network weights. The error function
+corresponds to the choice of output unit activation function. 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>[g, gdata, gprior] = glmgrad(net, x, t)</CODE> also returns separately 
+the data and prior contributions to the gradient.
