Re: Perl recipe for turning lines of numbers into an array?

I thought you will get those lines from a file, and that's why I gave that example with <DATA>. 

Glad it works.

By the way, I jused used the functionality  of open to open my string as a
stream, and your snippet worked like a charm.

Thanks much!

Take care,
Sina

This code does what you need:

my @array;

push(@array, [split(" ", $_)]) while <DATA>;

#Print the array to see if it is ok
use Data::Dump ('pp'); print pp(\@array);

__DATA__
298.25 1.2 -4
-194 1.239 -0.051
1.2 -253.221 100.24

Hi all,

I've got the following data, which I know will always be 14 rows long and
14
columns wide. The data is floating point numbers, the columns are
separated
by spaces, and the rows are separated by new lines ... Here's a 3 by 3
example of the 14 by 14 data.

298.25 1.2 -4
-194 1.239 -0.051
1.2 -253.221 100.24

How can I turn that into an array with indicies 0 through 2 which each
have
0 through 2 cells?

In other words a two dimensional 3x3 array with 9 elements?

Keep in mind numbers can be positive, negative,  and can have decimals.

If we have this in $matrix, how can we turn it into an array?

Thanks

Take care,
Sina
