+Description
+</h2>
+<CODE>g = mlpbkp(net, x, z, deltas)</CODE> takes a network data structure
+<CODE>net</CODE> together with a matrix <CODE>x</CODE> of input vectors, a matrix 
+<CODE>z</CODE> of hidden unit activations, and a matrix <CODE>deltas</CODE> of the 
+gradient of the error function with respect to the values of the
+output units (i.e. the summed inputs to the output units, before the
+activation function is applied). The return value is the gradient
+<CODE>g</CODE> of the error function with respect to the network
+weights. Each row of <CODE>x</CODE> corresponds to one input vector.
+
+<p>This function is provided so that the common backpropagation algorithm
+can be used by multi-layer perceptron network models to compute
+gradients for mixture density networks as well as standard error
+functions.
