Hi,

I am trying to create a matrix where I have removed selected months and years. Here is what I have so far:

dv=datevec(date); %where dv(:,1)=year, dv(:,2)=month and dv(:,3)=day

How do I remove summer of 2009 (i.e., dv(:,1)=2009, dv(:,2)=7 and dv(:,2)=8) and create a new dv?

Thanks!

idx = dv(:,1) == 2019 & ismember(dv(:,2),[6,7,8]); 
dv2 = dv(~idx,:); % to create a new dv
dv(idx,:) = [];   % to remove from existing dv

Ah yes. I was just about to ask about your answer until you edited it. This makes more sense. Thanks!

Yeah, I switched the last two lines in case they were both run on the same dv vector. Those two lines are two options to choose from.
