hello, im working on a project with matlab and arduino+adafruit motor shild; to control a stepper motor. i've conected to the arduino board thorow to arduino software and succeed to contorl the motor. my problem is when im using matlab code to control the motor i get this

a = arduino('COM4'); Attempting connection ................ Basic I/O Script detected ! Arduino successfully connected !

but what i really need is to conect with the adafruit motor shild and what i get is

a = arduino('com4', 'uno', 'Libraries', 'Adafruit\MotorShieldV2'); Error using arduino Too many input arguments.

can someone help me?

I have the same problem. Did you manage to figure out what was wrong? I see the arduino function in arduino.m does only take one input argument. Is there a different arduino.m file required?

Thank you in advance for any assistance.
