Re: Help Request

[Juan Pablo Carbajal]

Hi Vincenzo,

Please, always answer to the mailing list as well. I may be busy and
other people may help you before I go back to your question.
Additionally, you never knwon if other people will have a similar
problem in the future, and if they do our answers can be find in the
mailing list archives. We are not a help group or a customer service,
we just people like you, helping others because we will like to be
helped when we need it.

First, since it has been a hot topic lately, I will comment on your
contribution. If you have examples that you found useful (or you just
think they are), do write some documentation and send it to the
mailing list. The Octave community will be happy to enhance the
documentation with your help.

Now, concerning your question. If you are using linux, I would suggest
you to get the latest stable (3.4.2, soon to be 3.4.3)
http://www.gnu.org/software/octave/download.html . You can compile it
your own (is really easy, just scan the config.log file to see what
you are missing, and it doest take long), however Jordi says there are
people offering pre-compiled versions for many linux flavors.

OK, if you have a complex text file, but there is a structure you
knwon. You can always use fscanf, fgetl, fgets, etc... to get the data
you need.
As in the latest stable version 3.4.2, "textread" is a core function
and works fine to me.

Cheers,
