I have a data set that is made up of measurements done every 6 hours over the course of a year. So that is 1460 for an ordinary year and 1464 for a leap year. I am having trouble grouping them so that the values of each 4x6 hour group is averaged into a day.

Each year is a vector.

There are a myriad of way to do this, one of them should be the code below.

data=1:12;%example data
data=reshape(data,4,[]);%reshape so each day is a column (hence 4 rows)
dayly_mean=mean(data,1);
