matlab code to control stepper motor with Motor shield and adruino

this is my code but when i run it, there is no respond for a very long time eventhough it don't give me an error

can you help me plz

clear all;

s1 = serial('COM6');

set(s1,'BaudRate',9600);

a = arduino();

clear a;

a = arduino('COM6', 'Uno','Libraries','Adafruit\MotorShieldV2');

shield=addon(a,'Adafruit\MotorShieldV2');

addrs=scanI2CBus(a,0);

M=stepper (shield,1,36);

M.RPM=400;

move(M,200);

pause(5);

move(M,-200);

release(M);

I understand that you are trying to control a stepper motor using an Arduino UNO and MATLAB.

If the code is not giving any error, but it is taking a very long time to execute, it could be due to several reasons.

To debug this issue, you could try the following steps:

• Ensure that the stepper motor is connected to the correct pins on the Arduino board and that there are no loose connections. Check that the motor is receiving enough power and that the motor driver is properly configured.
• The motor speed may be too low to see any movement. You can try increasing the RPM value to see if the motor moves faster.
• Try running the move(M, 200) and move(M, -200) commands separately to see if the motor moves in either direction. You can also try changing the number of steps to move to see if the motor responds.

I hope the these steps will help you identify the issue and resolve it. Should you require further information, please feel free to reach out to me. I will be happy to assist you further.
