i'm acquiring data from ni9234 and at the same time i'm collecting values from xbee i want these two codes to execute at the same time in a single matlab file

clc; close all; clear all;  
delete(instrfindall);
s = serial ( 'COM5', 'BaudRate', 115200);
set(s, 'Timeout',0.080482);
s.InputBufferSize =20;
tic
fopen(s);
data=fread(s);

this is xbee code

s = daq.createSession('ni');
s.addAnalogInputChannel('cDAQ2Mod1', 0, 'Voltage');
s.addAnalogInputChannel('cDAQ2Mod1', 1, 'Voltage');
s.Rate = 2000
s.DurationInSeconds = 20;
[data5,time] = s.startForeground;
ni code
