how to acquire data from this code to process it in another operation in realtime

% get connected devices
d = daq.getDevices
%create session
s = daq.createSession('ni')
%add analog channel s.addAnalogInputChannel('ID',channel num, 'measurement type')
s.addAnalogInputChannel('Dev1',0, 'Voltage')


% set rate of scan 4 scans/second , run for 3 seconds
s.Rate=1000;
s.DurationInSeconds=30;

v= s.Channels(1);
set(v)
%_____________________________
%%
v.TerminalConfig = ' Differential';
v.Coupling = ' DC';


%%
%start continuous aquisition and plot

h = s.addlistener('DataAvailable', @(src,event) plot(event.TimeStamps, event.Data/.001));
s.NotifyWhenDataAvailableExceeds = 200;
s.startBackground()
