Error sending data from Arduino to Matlab

I am trying to send temperature sensor data from arduino to matlab using serial communication. The temperature data are displayed on the Arduino serial monitor but I couldn't get the data in Matlab. The following error occurs. I've tried every possible ways to get the data by putting a pause(3) before fscanf but it still doesn't work.
Warning: Unsuccessful read: A timeout occurred before the Terminator was reached. 'serial' unable to read any data. For more information on possible reasons, see Serial Read Warnings. NaN
if ~isempty(instrfind)
fclose(instrfind);
delete (instrfind);
end
waitTime = 10;
s = serial('COM4','BAUD',9600);
waitTime = duration(0,waitTime,0);
t = datetime('now') - startTime;
while t < waitTime
fopen(s);
pause(3);
idn = fscanf(s);
fclose(s);
serialData = str2double(idn);
corrData = serialData;
disp(corrData);
end
clear a;
clear s;
