Upload data into arduino

So I am going to be uploading a data from matlab to arduino, and this data will be constantly changing. I was thinking about just uploading a text file, but I was wondering whether arduino will update the change in the text file continously?

Or is there any other suggestion as to how to go about this?

For receiving data in an Arduino have a look at Serial Input Basics

...R

Do you have an idea as to why the error might have risen?
