I'm currently doing project to control a robotic car , but i need build a Matlab GUI to control the car through my laptop, so how i can interface Matlab with the Arduino to control the motor? i use 2 DC motor which is connect with H-bridge L293D, i can control the motor by using Arduino, but i have no ideal to interface the Arduino with the Matlab GUI, is any example or useful guide for me to interface both of them ???

Why Matlab? Matlab is a very expensive program to use for this task, unless there are requirements that you have not revealed.

yup, this is one of the my project requirement..., i follow the guide from there, but it shows this :
a=arduino('port')
??? Undefined function or method 'arduino' for input arguments of type 'char'.


i'm missing some step????

There is a link on the playground page to a mathworks site. It would appear that other people have been able to get all the required software installed so that MATLAB can talk to the Arduino. You should be able to, too.

There appears to be a fair amount of information available on the mathworks site, with examples, even.
