you can either (1) use a plain text editor and separate your
columns with a certain character ("," and "tabs" are the most
common ones) and then read the file into Octave [1], or (2) use
excel/gnumeric or whatever spreadsheet you like to enter and
manipulate your data and therein and then export it (Save as)
in CSV format (comma separated). Such files can be easily
read into octave with a command like,

X = aload("data.csv", Inf, Inf, ",");

that i've copied & pasted from Dirk Eddelbuettel, "Econometrics
with Octave", Journal of Applied Econometrics, Vol. 15, No. 5,
pp. 531-542, December 2000, available at

The 'aload' function above is part of the octave-ci package, which
facilitates the reading of ascii files. Iit is available at

Last, if you are running linux, give a try to G-octave, a
gnome interface to octave, supposedly (haven't tried it) it
is able to import CSV files and comes with a matrix editor,
sort of limited spreadsheet. It is available at

[1] see File I/O in the octave manual, or check the sourceforge
site at for extra functions.
