MATLAB: Accumulate in multiple array

averageunique

I have:
Temperature profiles array for 5 days. such that, temp(heigth,day). however, there are multiple profile in some days which makes the number of profile equal 11.
size of temp = (3650 by 11)
size of day = (1 by 11)
day=[1,1,1,2,2,3,3,3,4,4,5].
I want to:
average temperature for every similar days
such that:
dailyday=[1,2,3,4,5]
temp=(3650 by 5)
