Exporting data from a vector in a loop

[Nikke]

I have to export 2 vectors in 2 different .txt files. My entire program is a loop repeated about 250 times. At the end of every loop, I want to export the results (2 vectors, one is 1X8 and one is 1X4) in two different .txt files (ie: a.txt and b.txt). I've tried to use the function "dlmwrite" this way:

>>dlmwrite('a.txt', C, ';');
>>dlmwrite('b.txt, O, ';');

but the files are overwrited everytime the loop is repeated. So my solutions are twice but I really dunno how to do them:
1) Change the name of the .txt file for every loop I make, so that at the end of the program I have 250X2 files.
2) Create two tables where I write the values of C and O for every loop without overwriting the existing values, so that at the end of the program I have 2 files (two tables in this case) with 250 rows and 8 columns for the first file and 4 columns for the second file.

The second solution is the better for me and maybe is simplier too.

Why do you not use dlmwrite with the -append switch?

I'll try that thx.

Anyway I think I've solved by using a matrix for data storing instead of a vector, and by switching rows at every loop. Seems it works well.

Thanks for the tip!
