convert to gnuplot "grid data mapping" format

[Stefan Pofahl]

Hello,

sometimes you like to plot your 3D-Data via
Gnuplot from a data file.
To do that, it is best you have a "GnuPlot-Grid-Data-mapped"
file.
The special thing are the blank lines in this data file.
Imagine you have a three column file:
x, y, z

Than for a grid (3X3) the first block of the tree
blocks looks like:
x1, y1, z(x1,y1)
x1, y2, z(x1,y2)
x1, y3, z(x1,y3)
(blank line)

So now my question are there octave functions
known, that prepare data files like that?

Kind regards,

Stefan
