Subject: help with reading part of textfile into matrix

Dear all,

I am new to Ruby and I'm looking for a way to use Ruby (1.8) to read a part of 
a textfile into a matrix.

The textfile lokks like:

=== Confusion Matrix ===

     a     b     c   <-- classified as
  7494  4044   100 |     a = WEL
  2039 18691    11 |     b = NIET
   707   293   441 |     c = NOOIT

So what i want is that this matrix is read into a matrix variable in a ruby 
program which I can use then to manipulate in every way I want.

Can someone help me with this?

I figured out that I could maybe use a regexp /\s*a\s*/ to search for the line 
with a b c
Then I skip that line and start to read the following line position by position 
into the first row of the 3-by-3 matrix.

How could this be done?

Thanks in advance,
Robert Gilaard
