wolffd@0

30 data structure <CODE>net</CODE> together with a string <CODE>type</CODE> containing

wolffd@0
|
31 the correct network type, a matrix <CODE>inputs</CODE> of input vectors and checks
|
|
wolffd@0

32 that the data structure is consistent with the other arguments. An empty

wolffd@0
|
33 string is returned if there is no error, otherwise the string contains the

wolffd@0

34 relevant error message. If the <CODE>type</CODE> string is empty, then any

wolffd@0

35 type of network is allowed.
