| Daniel@0 | 25 Description |
| Daniel@0 | 26 </h2> |
| Daniel@0 | 27 <CODE>e = rbferr(net, x, t)</CODE> takes a network data structure <CODE>net</CODE> together |
| Daniel@0 | 28 with a matrix <CODE>x</CODE> of input |
| Daniel@0 | 29 vectors and a matrix <CODE>t</CODE> of target vectors, and evaluates the |
| Daniel@0 | 30 appropriate error function <CODE>e</CODE> depending on <CODE>net.outfn</CODE>. |
| Daniel@0 | 31 Each row of <CODE>x</CODE> corresponds to one |
| Daniel@0 | 32 input vector and each row of <CODE>t</CODE> contains the corresponding target vector. |
| Daniel@0 | 33 |
| Daniel@0 | 34 <p><CODE>[e, edata, eprior] = rbferr(net, x, t)</CODE> additionally returns the |
| Daniel@0 | 35 data and prior components of the error, assuming a zero mean Gaussian |
| Daniel@0 | 36 prior on the weights with inverse variance parameters <CODE>alpha</CODE> and |
| Daniel@0 | 37 <CODE>beta</CODE> taken from the network data structure <CODE>net</CODE>. |
