implicit_plot.lisp



Dear Andrej,

Many thanks indeed for providing such a nice package in implicit_plot.lisp

I'd like to capture the output for subsequent inclusion in a publication. 
I normally do this with

plot2d(x^2,[x,-2,2],[gnuplot_out_file,"test0.plt"])$

and then edit this to use the psTricks terminal of GNUplot.  However, the 
following does not work.

implicit_plot(x^2+2*y^3=15, [x,-10, 10], [y,-5,5],[gnuplot_out_file,"test1.plt"])$

Any suggestions?

Many thanks indeed,

Chris Sangwin
