Extract structure array elements into seperate matrix

I have a structure array with two fields that has multiple sets of information:

data(1).setnum = 1; % Contains integers to count set numbers
data(1).datablock = [1 2 3; 4 5 6; 7 8 9]; % Contains a matrix of numeric elements.
data(2).setnum = 2;
data(2).datablock = [1 2 3; 4 5 6; 7 8 9];

I would like to extract a specific element from each block of data to form a new matrix. For example I would like the element (1,2) from each datablock so that my new matrix becomes the following.

extracted = [2, 2];

I was attempting to use the line following but run into an error.

extracted = [data.datablock(1,2)];
Expected one output from a curly brace or dot indexing expression, but there were 2 results.

I found the following article, which basically says that what I'm trying to do is impossible by this method, but the article is two years old, so I'm looking to confirm that this method is still not possible, or if I have made some kind of syntax error.

No, that syntax won't work. If you want a one-liner, here's one alternative:

extracted = cellfun(@(x) x(1,2), {data.datablock});
