Question

I am trying to streamline my code. I have a 2-column array from which I’d like to extract the averages of the columns and store them as X and Y.

I tried using the following code:

[x y] = mean(theArray);

…However, this returns

??? Error using ==> mean
Too many output arguments.

For now, I have settled with the three lines:

coords = mean(theArray);
x = coords(1);
y = coords(2);

I’m sure there must be a much simpler way of doing this in less than three lines. My code is running an eye tracking device at 1000Hz and I want to avoid any unnecessary processing…

Any wisdom gratefully received

Answer 1

In two lines:

x = mean(theArray(:,1));
y = mean(theArray(:,2));
