This ..., well ..., it doesn't work. At first I thought that you meant
@entry[x] in your last line, but that doesn't help either. I always get
3 pairs of commas without the values. Besides, the way I read the code,
it doesn't do anything usefull, because a line with values seperated by
commas, will become exactly the same line. But then again, I don't know
anything about Perl, so this is just guessing.

What about matrixes with a different number of columns and rows (e.g.
4x3 or 123x234)?
