| 26 Description | |
| 27 </h2> | |
| 28 | |
| 29 <CODE>e = glmerr(net, x, t)</CODE> takes a generalized | |
| 30 linear model data structure <CODE>net</CODE> together with a matrix <CODE>x</CODE> | |
| 31 of input vectors and a matrix <CODE>t</CODE> of target vectors, and evaluates | |
| 32 the error function <CODE>e</CODE>. The choice of error function corresponds | |
| 33 to the output unit activation function. Each row of <CODE>x</CODE> | |
| 34 corresponds to one input vector and each row of <CODE>t</CODE> corresponds to | |
| 35 one target vector. | |
| 36 | |
| 37 <p><CODE>[e, edata, eprior, y, a] = glmerr(net, x, t)</CODE> also returns | |
| 38 the data and prior components of the total error. | |
| 39 | |
| 40 <p><CODE>[e, edata, eprior, y, a] = glmerr(net, x)</CODE> also returns a matrix <CODE>y</CODE> | |
| 41 giving the outputs of the models and a matrix <CODE>a</CODE> | |
| 42 giving the summed inputs to each output unit, where each row | |
| 43 corresponds to one pattern. | |
