nnet in Octave-5.1.0.0 it doesn't work

[Toni Francesca]

Hi,

 

I am a new user in Gnu Octave. I started working on the Neural Network package (nnet 0.1.13).

I tried the example 1 (MLP9_1_1.m) in the installation folder but didn’t work, the error message is :

 

error: 'df_mapper' undefined near line 22 column 10

error: called from

    finite at line 22 column 8

    tansig at line 38 column 5

    __calcperf at line 85 column 21

    __trainlm at line 107 column 19

    train at line 125 column 11

    MLP9_1_1 at line 91 column 7

 

I use Octave 5.1.0.0 on Windows 7.

Could anyone help me?

Thanks!
