I am processing ocean and climate data (1982-2022). Here, I have table which having heatwaves events details. Now, I want to sort the data month wise and also seasonal wise (summer:October- February, and winter:March-September), and then i wanted to plot mean seasonal and trend.
Sample file is attached. length of original file may vary in size.
Thanks in addvance.

Yes, I can understand the code now, but not sorted out my problem.
load table_1.mat
MHW3.mhw_onset = datetime(MHW3.mhw_onset,"ConvertFrom","yyyymmdd");
MHW3.mhw_end = datetime(MHW3.mhw_end,"ConvertFrom","yyyymmdd")
Here after, I need to extract only the summer (October- February), and winter (March-September).
So, now I am searching code for this. Its great if you could share code.

Does this work?
load table_1.mat
MHW3.mhw_onset = datetime(MHW3.mhw_onset,"ConvertFrom","yyyymmdd");
MHW3.mhw_end = datetime(MHW3.mhw_end,"ConvertFrom","yyyymmdd");
% extract summer data
MHW3_summer = MHW3(month(MHW3.mhw_onset)>=10 | month(MHW3.mhw_onset)<=2,:);
% extract winter data
MHW3_winter = MHW3(month(MHW3.mhw_onset)>=3 & month(MHW3.mhw_onset)<=9,:);
