Dear friend,

     Do you know/have any mathematical software that can plot 3D-graph from
input data and even able to generate the f(x,y) equation from the same
graph? please response (reply to my email if any), thanks!


Regards,
Chee Hong, Lee

The program for plotting this data is GNUPLOT (http://www.gnuplot.vt.edu/). I
don't know any program or algorithm for generally reconstruct the equation,
but depending on your data you may have a look at the Lagrange- or
Spline-interpolation.
