Hi,
Being used to deal with Octave / Matlab, I'm a bit confused by Ruby
structures (arrays, hashes, etc). I have this data file "data.dat"
with 3 columns:
I would like to think of the columns as arrays "a", "b", "c", execute
a loop along their indices, pick the values i want, and do something
with them. What would be a sensible data structure for this?
I can read this datafile line by line using IO:readlines("data.dat"),
but I cannot find a way to refer to one column in the array of
strings generated.
Best regards,
baptiste
