making a table

J G — Sun, 22 Aug 2010 22:27:06 +0000

Is it possible to have output data directly entered into a table? I have a loop which produces a series of vectors (one for every time the loop is run), eg.

1 2 3 4

5 6 7 8

etc. lets say for 100 times, and I would like this to be directly entered into a table every time the loop spits out another vector (the same table), ie. with 4 columns, 100 rows.

Assuming a "table" is simply a 2D array (matrix)

x = zeros(100,4);
for idx = 1:length(x)
x(idx,:) = your_function_output(whatever_its_input);
end

In MATLAB, "table" is used with respect to several technologies that are
internally quite different. Could you be more specific about what you
are wanting to do? For example, is this a question about uitable, or is
it a question about connecting to an SQL server?

Sorry, I meant a uitable. Thanks

Please see
http://www.mathworks.com/matlabcentral/newsreader/view_thread/281187 for
information on doing direct uitable updates.

You might have some logistic difficulties with respect to the entries
that you have not really initialized yet.
