Grouping vector data based on different intervals

Hi community,

I have vector data with values for each hour in a year (i.e 24*365 = 8760 vector length).

I'm just looking for simple tips to group data based on intervals, like :

1) Sum of values per day (interval 24) in a vector with length 365...

2) Sum of values per hour for each day in a vector with length 24...

Thanks to all !

Sounds like it would be better to have your data organized as a 24x365 matrix instead of as a vector.

A=reshape(data,24,365);
sum(A,1)
sum(A,2)
