Hi,


A basic question: how to extract several consecutive lines of numbers  
in a text file (example below) and assign them to some GSL::Matrix in  
Ruby?

text file:

> some lines of text ...
> ....
> more text
> below is the data to extract
>
> 1 2 3
> 4 5 6
> 7 8 9
> 23 7.3e-8 3.4
>
>
> some more text


from which i would like to create three vectors, a=[1, 4, 7, 23], b=  
[2, 5, 8, 7.33-8], c=[3, 6, 9, 3.4]. The line numbers could be used  
for indexing if that can help.

Many thanks,

baptiste
