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

Instead of a stream like <DATA>, can I use a variable like $matrix?

The data is currently inside of a string.

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
