| 24 Description | |
| 25 </h2> | |
| 26 <CODE>g = gpgrad(net, x, t)</CODE> takes a Gaussian Process data structure <CODE>net</CODE> together | |
| 27 with a matrix <CODE>x</CODE> of input vectors and a matrix <CODE>t</CODE> of target | |
| 28 vectors, and evaluates the error gradient <CODE>g</CODE>. Each row | |
| 29 of <CODE>x</CODE> corresponds to one input vector and each row of <CODE>t</CODE> | |
| 30 corresponds to one target vector. | |
