a= 80;
csvwrite(num2str(a), [2]);

the result = 80.dat

what can I do so that the file name can be 80_1?

csvwrite(num2str(a,'%d_1.dat'),[2]);

i really can't see anything wrong with the codes below,
it has the bracket unbalanced error, but it has 4 pairs
brackets which is right....

csvwrite ((num2str(ceil(handles.randValue)),'%d_1.dat'), [1]);

Just because you have 4 of each doesn't mean it makes
sense... you have the wrong number of arguments for your
functions. You need this:

csvwrite(num2str(ceil(handles.randValue),'%d_1.dat'), [1]);

Also the square brackets arent doing anything. Though it
seems like you want something other than "1" for your last
argument anyway... you realize this will just output a text
file with the number 1 in it, right?

thanks for that. Yea, I know it will just output a text file
with the number 1.

Ideally, I want to have different arrays when the function
is called everytime, something like this...

Callback 1= [1, 2, 3])
Callback 2= [Callback 1: 4, 5, 6])
Callback 3= [Callback 2: 7, 8, 9])
Callback 4 = csvwrite ('string', [callback 3+ callback 4])

that means, the last callback is collecting all the data and
output it as a text file.

not sure how to do it though......
