I have a script that I want to run automatically, every 5 seconds. How could I set this up so that it runs in an unattended manner?

Do you need to run the script from the beginning every five seconds, or would running a script that loops indefinitely and polls for data to process every five seconds be sufficient?

The script actually consists on importing variables from an OPC server coming from a PLC, make a prediction for a new variable using neural networks, then write this new predicted variable to the OPC server (see code below). So, I think the script should be running systematically in order to retrieve new data from the input variables, and write the new predicted value of the output to OPC server.
%% OPC connection
da= opcda('Localhost', 'Matrikon.OPC.SiemensPLC.1');
connect(da);
%create Group
grp = addgroup(da, 'YYY');
%Add Tags
additem(grp, {'TCP CHANNEL>YYY>FeedRate', 'TCP CHANNEL>YYY>Reject', 'TCP CHANNEL>YYY>puissanceelevderecirc', 'TCP CHANNEL>YYY>Clinker','TCP CHANNEL>YYY>Limestone', 'TCP CHANNEL>YYY>RegistreRecirculation' , 'TCP CHANNEL>YYY>Maindrivepower', 'TCP CHANNEL>YYY>Temperaturesortiebroy', 'TCP CHANNEL>YYY>Puissanceseparateur', 'TCP CHANNEL>YYY>pressionsortiebroyeur', 'TCP CHANNEL>YYY>Electronicear', 'TCP CHANNEL>YYY>Gypsum'});
%Retrieve Data
r = read(grp);
%r(:,1).Value
X = extractfield(r,'Value').';
%Clean up
disconnect(da)
delete(da)
%% Predict output
Y = MatlabMatrixonlyfunction(X)
%% OPC Write
da = opcda('Localhost', 'Matrikon.OPC.SiemensPLC.1');
connect(da);
grp = addgroup(da, 'DemoGroup');
itmIDs = {'TCP CHANNEL>YYY>FinesseLaboratoire'};
itm = additem(grp, itmIDs);
% read and write values to and from the items
write(itm, Y);
R45predite = read(itm);
