Is there a command to index months in a timetable series?
I would like to index one long term timetable in two ways. In one, all July, August, and September are indexed. In the second Novemeber through March are indexed.
My timetable is a daily series.

Logical index of rows that are in July,Aug,Sept.
idx = ismember(month(TT2_staLCA_WS.Time),[7,8,9]);

It's just basic indexing.
For example,
T = table((1:5)',["A";"B";"C";"D";"E"])
% T =
% 5×2 table
% Var1 Var2
% ____ ____
% 1 "A"
% 2 "B"
% 3 "C"
% 4 "D"
% 5 "E"
idx = ismember(T.Var1, [1,3,4]) % rows where var1 is 1,3,or 4
% idx =
% 5×1 logical array
% 1
% 0
% 1
% 1
% 0
% EXAMPLES OF INDEXING
T(idx,:)
% 3×2 table
% Var1 Var2
% ____ ____
% 1 "A"
% 3 "C"
% 4 "D"
T.Var2(idx)
% 3×1 string array
% "A"
% "C"
% "D"
