Accessing cell array contents

I have a one-dimensional cell array where each element of the array contains a timetable with identical format. Is there a direct way of creating a vector that contains the last element of one specific variable in each timetable (without looping)?
For example, something like:
CellArray{:}.Variable(end)

No. You could use cellfun, but that will only hide the loop. Using a loop directly tends to have better efficiency.
But don't worry: loops are not as bad as you might think (especially if you pre-allocate the output). They are only bad when there isn't a builtin equivalent that operates on the entire array.

+1 Rik, @Dave O if a loop is more readable to you than cellfun, go with the loop.

In this example, the cell array is named myCellArray and the variable is named myVar.
y = cellfun(@(A)A.myVar(end), myCellArray)
If the values you are extracting are non-numeric or non-scalar,
y = cellfun(@(A){A.myVar(end)}, myCellArray)
