Hey @Temu Gautama
The following part works perfectly
tmp.eventid(rem(tmp.eventid+1,4)>1));
However when I'm doing the following it doesn't seem to work. What I mean is from all results it now removing rows with eventid 1,2 keep...3,4 remove....5,6 keep....7,8 remove so on....
tmp = allresults;
tmp = tmp(find(tmp.eventid(rem(tmp.eventid+1,4)>1)),1:4);

请先登录,再进行评论。

If you have an array A...To remove a specific element use:
A(A==val) = [] ;
