TF = isequaln (A, B) is identical to isequal (A, B) except that missing values are treated as equal to one another, in the same way that isequaln treats NaN. Two timetables whose row times are NaT in the same places are therefore equal, where isequal calls them unequal.

Further timetables may be supplied, as in isequaln (A, B, C, …), in which case TF is true only when all of them are equal to one another. Any argument that is not a timetable, a table included, makes the result false rather than raising an error.
