How can I use my own transfer function

I'm using Matlab2008. There is file template_transfer.m and rename it : fungsiku.m. I write down my function in this file and put it in my working directory. But, I got the outputs and some messages like this

Exception in thread " AWT-EventQue...."
at javax. swing..
at java.awt

.. and the script didnt stop.
What should I do? Thank you.

Do you want to write a simple function or a transfer function?

[Nn Sagita]

Thank you for your response. I want to write my own transfer function. Beside i got the output, i got some messages like that. Here is the code of my transfer function (name: fungsiku)

 function out1 = fungsiku(in1,in2,in3,in4)

fn = mfilename;
boiler_transfer

 function n = name

    n = 'fungsiku';

 function r = output_range(fp)

    r = [-6 +5];

 function r = active_input_range(fp)

    r = [-10 +10];

 function fp = param_defaults

   fp = struct;

 function names = param_names

   names = {};

 function err = param_check(fp)  

    err = '';

 function a = apply_transfer(n,fp)

    a = 1.32*n + 0.73;

 function da_dn = derivative(n,a,fp)

     da_dn = 1.32*ones(size(n));

What should I do?

I had the same problem. It is because nntraintool. So I disappear nntraintool while training process using below code,

net.trainParam.showWindow=0;

It worked for me.

I think this will help u.
