Daniel@0 26 Description
Daniel@0 27 </h2>
Daniel@0 28
Daniel@0 29 <CODE>e = glmerr(net, x, t)</CODE> takes a generalized
Daniel@0 30 linear model data structure <CODE>net</CODE> together with a matrix <CODE>x</CODE>
Daniel@0 31 of input vectors and a matrix <CODE>t</CODE> of target vectors, and evaluates
Daniel@0 32 the error function <CODE>e</CODE>. The choice of error function corresponds
Daniel@0 33 to the output unit activation function. Each row of <CODE>x</CODE>
Daniel@0 34 corresponds to one input vector and each row of <CODE>t</CODE> corresponds to
Daniel@0 35 one target vector.
Daniel@0 36
Daniel@0 37 <p><CODE>[e, edata, eprior, y, a] = glmerr(net, x, t)</CODE> also returns
Daniel@0 38 the data and prior components of the total error.
Daniel@0 39
Daniel@0 40 <p><CODE>[e, edata, eprior, y, a] = glmerr(net, x)</CODE> also returns a matrix <CODE>y</CODE>
Daniel@0 41 giving the outputs of the models and a matrix <CODE>a</CODE>
Daniel@0 42 giving the summed inputs to each output unit, where each row
Daniel@0 43 corresponds to one pattern.
