As shown in the JSL below, in the case of a Matrix, 'loc' can be used to display indices greater than 5, but it cannot be applied to a List. How should I find the indices greater than a certain value in the case of a List?
show(Loc( [5, 7, 3, ., 5] >= 5 ));
show(Loc( {5, 7, 3, ., 5} >= 5 )); //Error
