merge 12 rows in 12 matrices to one matrix

I have daily RF data for 55 years and I managed to get mean monthly RF for 55 years for each months seperately. I want to get all mean monthly RF data into one table. How can i do it.

My daily RF data is 365X55

mean for January is 1X55

mean for February is 1X55

Now I need January to December in one table 12X55

Rather than taking one by one mean values for each months, is it easy way to get directly 12X55 matrix?

Please help, Thanks in advance

I'll define some fake data:

nMonths = 12; 
dailyRF = rand(365,55);                 % fake data array
idxDays = [31; 28; 31; 30; 31; 30; ...  % days in each month
           31; 31; 30; 31; 30; 31]; 

idx1 = cumsum(idxDays) + 1 -idxDays;    % start index
idx2 = cumsum(idxDays);                 % end index 

avgMonth = zeros(12,55);                % pre-allocate

% Loop over the number of months and take average over entire month:
for k = 1:nMonths
    avgMonth(k,:) = mean(dailyRF(idx1(k):idx2(k),:),1); 
end
