How to find all roots of a function in two variables?
August 15, 2010 8:18 AM Subscribe
I've got a long function with two variables, encoding - I suspect - a hidden message. Most likely, the message is somehow encoded in the function's roots. Is there any good software to plot a function in two dimensions and only show the points where it evaluates to zero?

I've tried gnuplot and octave, but I couldn't get them to show what I wanted.
Do you have any ideas? Software for Linux or Windows is appreciated.
Other ideas how to encode a message in a function?
