How do I start coding for neural network time series?

Hi, I am very new with matlab and the neural network function. I am doing a public transport prediction data using this toolbox. I have watch the tutorials but I do not really understand. How do I start inputing the data and set the inputs and the targets. Thanks in advance

Examine the help examples for

timedelaynet, narnet, narxnet and closeloop.

Next try other examples

% input data from excel spreadsheet
Hourly = xlsread('C:\Users\user\Desktop\FYP\Datasheet.xlsx','Daily','A2:A25');
Weekday_Ridership = xlsread('C:\Users\user\Desktop\FYP\Datasheet.xlsx','Daily','B2:B25');
Weekend_Sat = xlsread('C:\Users\user\Desktop\FYP\Datasheet.xlsx','Daily','C2:C25');

t= Hourly;

% define signal
x1 = Weekday_Ridership;
% plot signal
figure;
plot(x1)
xlabel('Hourly');
ylabel('Ridership');

Target= Weekend_Sat;  %targets
net = newff(x1,Target,1);
net = feedforwardnet(4)
net = train(net,x1,Target);
view(net)
y = net(x);
outputs = net(x1);
errors = outputs - Target;
perf = perform(net,outputs,Target);

Hi, after much trying here and there, I still don't get it. I still get blank graphs.

My data is as below

I am suppose to do a prediction of the ridership of public transportation be over the next few days.

I hope you are able to help me. Thanks in advance.

Confused. Is the task to predict the ridership for the next 3*24 = 72 hours? It seems like you would at least, need the ridership for the last 4*24 = 92 hours.

You need continuation symbols after xlsread

 xlsread...

Hope this helps.
