Calculate a monthly average from 3-hour data

Hello everyone!

I'm having a little trouble trying to make a code to calculate the average or the mean for a set of data 90585x1.

This set have information every 3 hours from temperature from 1950 to 2010, I want to make those values a monthly average and after i've got my data set reduced plot.

I was looking to apply a for-lopp or an accumarray don't know how to make this, if anyone could help me, I will be so grateful

If you want to simplify slightly, 8 readings * 30 days/month = 240 readings per month ... = 377 months = 90480 readings. Truncate the rest of the readings.

T=T(1:90480);
T=reshape(T,240,[]);
m=mean(T);

I don't know if there's a problem with the months that don't have 30 days, maybe you know how to solve this ?

My assumption was that you could just live with every month having 30 days. I am not sure if you can live with that; if not, you code will be more complex.

I will try with 30 days per month! Thank you so much David!
