| 26 Description | |
| 27 </h2> | |
| 28 | |
| 29 <p><CODE>errstring = consist(net, type, inputs)</CODE> takes a network | |
| 30 data structure <CODE>net</CODE> together with a string <CODE>type</CODE> containing | |
| 31 the correct network type, a matrix <CODE>inputs</CODE> of input vectors and checks | |
| 32 that the data structure is consistent with the other arguments. An empty | |
| 33 string is returned if there is no error, otherwise the string contains the | |
| 34 relevant error message. If the <CODE>type</CODE> string is empty, then any | |
| 35 type of network is allowed. | |
| 36 | |
| 37 <p><CODE>errstring = consist(net, type)</CODE> takes a network data structure | |
| 38 <CODE>net</CODE> together with a string <CODE>type</CODE> containing the correct | |
| 39 network type, and checks that the two types match. | |
| 40 | |
| 41 <p><CODE>errstring = consist(net, type, inputs, outputs)</CODE> also checks that the | |
| 42 network has the correct number of outputs, and that the number of patterns | |
| 43 in the <CODE>inputs</CODE> and <CODE>outputs</CODE> is the same. The fields in <CODE>net</CODE> | |
| 44 that are used are | |

| 55 | |
| 56 <p><CODE>mlpfwd</CODE>, the function that propagates values forward through an MLP | |

| 62 error(errstring) | |
