my code body is
clear all;
clc;
close all;
comport=serial('COM5','Baudrate',9600);
fopen (comport);
x=0;
while(x<100)
x=x+1;
v1(x)=fscanf(comport, '%d');
plot(v1,'r--','linewidth',3)
grid on;
hold on;
end
fclose(comport);
delete(comport);

Is the arduino connected to COM5?
What happened when you use instrfind to find out what was already in use?
