How can i select rows in a timetable?

I have a time table created as follows

TT_T=timetable(T_T,a_X_T,a_Y_T,a_Z_T,w_X_T,w_Y_T,w_Z_T,Mag_X_T,Mag_Y_T,Mag_Z_T,Pres_P_T,Press_T_T,P_V_T);

T_T is a datetime column with this format

'10:49:26.724'

'10:49:26.726'

'10:49:26.729'

'10:49:26.731'

... it continues for 1 hour

I tried to select rows with "timerange"

A=timerange('10:53:32','10:53:38')

impact=TT_T(A,:);

But it shows me this error:

"A timetable with datetime row times cannot be subscripted using duration values."

One option is to convert ‘T_T’ to a duration array, so timerange would work with it.

Another option is to use logical indexing —

tr = [datetime('10:53:32') datetime('10:53:38')]                    % Time Limits
Lv = (TT_T.T_T >= tr(1)) & (TT_T.T_T <] tr(2));                     % Logical Vector
A = TT_T(Lv,:)

These could be combined into fewer lines. I separated them so that it would be more obvious.

I cannot test this, so I am posting it as UNTESTED CODE. I have used a similar approach in other situations, so I am reasonably confident that it will work, however it may need a few tweaks.
