I am trying to do the following.
I have a 7670 array of data
I also have complimentary arrays that are 7670 in length that are the day, month, and year
For instance
data = [1,7670] = [.3,.45,.56,.67, etc].....to index 7670 with just data values
day = [1,2,3,4,5...31,1,2,3,4,....28,1,2,3,4....30] repeating for 7670 indexes. These are the value of the days in the particular month
month = [1,1,1,1,1,(31 times), 2,2,2,2,2,2,(28 times), etc] for 7670 indexes
year = [1980,1980,1980, (365 times), 1981,1981, (365 times),] etc for 7670 indexes
My question is how can I take this daily data and average it for each month...so my 7670 array is about 650 in length
Here is what I have right now. This is matlab

Code:
count = 1;
for i=1:7670
if i < 7670
while day(i+1)>day(i)
k = 1;
index(count,k) = day(i);
k = k+1;
end
u300_PC1_monthly_avg(count) = mean(u300_PC1(index(count,1):size(index,2)));
count = count+1;
i = i+1;
end
end
