I want to calculate the mean over multiple points in a plot.
y = [12 17 16 15 56 45 24 86 65 41];
x = length(y);
now I want the mean over the first two points the second two points etc. But my real dataset is bigger than these 10 points so I need a loop for it, but don't know how to do it.

mean(reshape(y,2,numel(y)/2))

Thank you, my next problem with the real dataset, is that it gives me the following error:
Size arguments must be real integers.
how do i solve this?

I guess that the number of element in y is an odd number. This conflicts with your averaging.
Try
Z=[mean(reshape(y(1:end-1),2,numel(y(1:end-1))/2)),y(end)]

this function works but when I wanna change the number of values tot mean, it will give the same error.
so, when i want to change the 2 into 60 values it doesn't work

Is the lenghth of the y-array divisible by 60 ? What do you want to do if this is not the case ?
