Calculating mean over multiple dimensions

I have a 3-dimensional variable that is of the class double, example: data has 50x2000x999. I would like to compute the mean for the 3rd dimension first, then the second dimension, and then the first dimension.

I know one way to do this is:

meandata = mean(data,3)

meandata = mean(meandata,2)

meandata = mean(meandata).

Is there a more efficient way to do this? In one line of code probably?

Thanks,

Akul

mean(data,'all') % or
mean(data,[3 2 1])

mean(data(:))
