newrb using existing dataset

i try using newrb to train rbf using the dataset

the 1st to 6th column is the signal strength

the 7th column is the x-coordinate and 8th column is the y-coordinate

what i want to achieve is to predict the coordinate from the signal strength

this is my attempt at coding

clc

clear all

close all

%% input data

data = load('Data_positioning.csv');

p = data(:, 1:6);

t = data(:, 7:8);

%% create radial basis function Neural Network

net=newrb(p,t,0.1,1,100,10);

view(net)

results=sim(net,p);

%% Plots

scatter(t,p);

hold on;

plot(p,results,'LineWidth',2,'MarkerSize',10);

R=regression(t,results);
