RE: large input data

[Frank Palazzolo]

Hi,

An observation - if you plan on processing the same datasets over and over,
I've found it very worthwhile to resave them as binary files, and use those
from that then on.  Loading of files is much faster once the text parsing is
eliminated.

Similar requirement.  Sometimes the data is scooped up from
an Excel spread sheet, or sometimes just a lot of terms. 

I use a text editor (sometimes notepad) to make an ascii
data file, dataset.txt.  Include "fake" headers at the top
of the file [those five lines at the top, describing what
the data is] to make it look like a standard ascii style
octave file.  

then use...
>> load -force "dataset.txt";
...to load it in, and overwrite the specific variable.
