| Daniel@0 | 26 Description |
| Daniel@0 | 27 </h2> |
| Daniel@0 | 28 <CODE>y = mlpfwd(net, x)</CODE> takes a network data structure <CODE>net</CODE> together with |
| Daniel@0 | 29 a matrix <CODE>x</CODE> of input vectors, and forward propagates the inputs |
| Daniel@0 | 30 through the network to generate a matrix <CODE>y</CODE> of output |
| Daniel@0 | 31 vectors. Each row of <CODE>x</CODE> corresponds to one input vector and each |
| Daniel@0 | 32 row of <CODE>y</CODE> corresponds to one output vector. |
| Daniel@0 | 33 |
| Daniel@0 | 34 <p><CODE>[y, z] = mlpfwd(net, x)</CODE> also generates a matrix <CODE>z</CODE> of the hidden |
| Daniel@0 | 35 unit activations where each row corresponds to one pattern. |
| Daniel@0 | 36 |
| Daniel@0 | 37 <p><CODE>[y, z, a] = mlpfwd(net, x)</CODE> also returns a matrix <CODE>a</CODE> |
| Daniel@0 | 38 giving the summed inputs to each output unit, where each row |
| Daniel@0 | 39 corresponds to one pattern. |
