how to remove a particular season values from monthly time series?

3 views (last 30 days)
Hello everyone,
I have monthly temperature data for 20years (360x720x240) where 360x720 is latitude x longitude. From this monthly time series, I want to remove the winter season (December, January, Fabruary months), so the final outcome will be 360 x 720 x 180 (9month timeseries for 20 years)
How can remove these three months from every year?

Assuming the data is stored as a double array and the season data is month wise i.e Jan-Feb-...-Nov-Dec
y = rand(360,720,240);
ans = 1×3
360 720 240
%Delete the values corresponding to winter months
y(:,:,[1:12:end 2:12:end 12:12:end])=[];
ans = 1×3
360 720 180

thedates = (datetime(2003,1,1):days(30):datetime(2023,12,31))' ;
idx = thedates.Month == 1 | thedates.Month == 2 | thedates.Month == 12 ;
iwant = thedates(~idx) ;
