could anyone help me to correct this code. i just need a bit of help.

1. inserting anchor nodes in both asp and neural network methods
2. correction factor uses anchor node as input.
3. training in neural network uses original location..that is input and output are same..

[Greg Heath]

Please explain,

 1. Inputs
 2. Targets
 3. The purpose of the function outputs = f(weights,inputs)

What is asp?

What is an anchor node?

[shafeena]

sir, how could i upload a zip file?it containing all data..i just mailed to you..could you pls check it

[shafeena]

anchor node means position known nodes. asp means adhoc positioning system..it is for localization using hop count

[Greg Heath]

Definition of inputs and outputs?

Sorry. I do not help via email.
