I have a series of 365 days. I need to divide the elements of the array into months with 31, 28, 31, 30 .. days and add the values ​​for the months.
The result should be a series of 12 months with aggregated values ​​for each month.

Convert to a timeseries() object and use retime()
Or:
Data = rand(365,1);
Data_timestamp = datetime(2021, 1, 1:365).';  %use non-leap year !
month_totals = accumarray(month(Data_timestamp), Data)
month_totals = 12×1
