I've had mostly good luck with SciLab but its read of CSV files is pretty s=
low.

One thing I do to speed it up a bit is tell SciLab which columns I'm intere=
sted in reading.  Then the very next command after "read" is a write to pus=
h the data back out into a SciLab data file.  Those read and write much fas=
ter.=20

I had much the same problem with MatLab when I used it years ago.  I think =
the problem comes in SciLab (MatLab) allocating memory on the fly to store =
the matrix.
