How can I take the datas from comport?

I have a code in ardunuio. Also this is just an example. that code will write the datas to comport. I want to read the integer datas. So ı am trying to read U firstly and then ı am starting to take integer data but ı could not take. How can I take like that?

comport = serial('COM3','BaudRate',9600);
fopen(comport);
for i=1:100
angles=fscanf(comport);
if(angles=='U')
   phi=fscanf(comport,'d');
   theta=fscanf(comport,'d');
end
end
fclose(comport);
delete(comport);

Instead of fscanf(), try using

oneByte = fread(comport, 1);

this will read one value from the serial buffer. Also, you should note that since you are using Serial.println, the Arduino will also send newline character (value 10 in ASCII).
