Hi.

I have written a code (Untitled.m) with the aim of finding a correlation between a set of inputs and outputs (check SWat.mat).

The learning process has been carried out using a RBNN function (the newrb matlab function), and at the end I managed to generate a function (MyFun.m) in order to do some predictions.

For the sake of validation, I applied the "MyFun" function to some data (Test.mat), but for my surprise, I have got the same value for all the outputs which appeard to be significantly different for the the real values (Check Sw.mat).

I don't know if I have missed something when writing my algorithm (Untitled.m).

Any help or clue is welcome.
