This very well depends into what do you want to read it.

Is the blabla string important? If not, I would massage your data
first with a text munger (e.g. Perl) to remove that string and then
use Octave's ordinary "load" function to read your matrix.

If not, you may need to do your own parsing with C-style IO functions in Octave.
