Based on what you think the following two lines from your code:
a=["filename_folder"];
filenames=cellstr(a);
will collect file names from the directory ?
Yes, you are right. So, my result was not to be what I expected like my description on the previous email. Anyway, thanks very much for your explanation about array. It is very helpful for me to understand octave better.
Until now, I can not find what command to pick up/load my files into a matrix. I have already searched about "load" command, but I didn't find yet.
Finally, I used awk command to solve my problem eventhough awk is more time-consuming.
Again, thanks very much..
