Currently I am doing a PID controller and we have the data of the oscilloscope which is a sin wave. I want to be able to see which in which file there is the smallest error(the smallest sin wave's amplitude). I just downloaded Matlab today and I have almost cero knowledge. I hope someone can help

Hi,
You may use root mean square error as that results errors at quite minute rate.
For more info as to how to use it, you may take a look at below question:

Hope it helps !
