How do I create a for loop for averages?

I am trying to extract data from each column in order to produce averages for each year. i have posted an example of the script below:

year1 = RCP26(1,2:13);

year2 = RCP26(2,2:13);

year3 = RCP26(3,2:13);

average1 = mean(year1);

average2 = mean(year2);

average3 = mean(year3);

I need to create a for loop to create average for the years 1860-2100. when i try to do this i put in my for loop:

nYears = length(RCP26);

for i = 1:nYears

year(i) = RCP26(i,2:13);

end

however that does not work and im not sure why.

No need to use for-loop

averages = mean(RCP26(:,2:13), 2)

See the dim argument to mean() function: https://www.mathworks.com/help/matlab/ref/mean.html
