| One good way would be to use a parametric function: http://webwork.math.rochester.edu/docs/docs/pglanguage/pod/fun.html#new%20(parametric%20version) another more efficient way is to use the technique described in http://webwork.math.rochester.edu/docs/docs/pglanguage/pod/vectorfield.html toward the bottom of the page. (GD.pm is a perl module that has many more capabilities than have been documented for the PG language. ) This is all I have time to say at the moment. I can write an example for you next week if needed. Hope this helps. Take care, Mike |
