[Eeglablist] Electrodes Values

[Makoto Miyakoshi]

Dear Kleber,

>* How can I sum this electrodes values of the sample in a single value that
represents  the total of microvolts oh that "sample"?

People usually don't 'sum' them, but average them for a specified time
window.

>* How can I describe the values of "y" samples in a single value that
represents these "y" sample values?

Average them.
