Hi Matteo!
What I understood from your question is that you want to extract elements from all tables of the given position.
The method which you are using is fast one only. Also you can look through the below code, which may also work.
% initialize cell array
Tarray = cell(1, n);
% populate cell array with tables
for i = 1:n
Tarray{i} = readtable("table_" + i + ".csv");
end
% use cellfun to extract scalar value from each table
arr = cellfun(@(table) table{2, 3}, Tarray);
cellfun(func,C) applies the function func to the contents of each cell of cell array C, one cell at a time. cellfun then concatenates the outputs from func into the output array A, so that for the ith element of C, A(i) = func(C{i}). The input argument func is a function handle to a function that takes one input argument and returns a scalar. The output from func can have any data type, so long as objects of that type can be concatenated. The array A and cell array C have the same size.
Please refer to these documentation for more information on 'cell' and 'cellfun':
Hope this answer your query.
