# Drawing complex integration contours

Hi!

I'm writing some lecture notes and I need to draw some complex integration contours. Is there any software to make this task easier?

Thanks for your attention!

If you have TeX I recommend asymptote, if you don't I recommend Geogebra.

Why not make PostScript pictures? You only need a few commands to define even quite complicated contours.

Hello, thanks for your replies. I´ll look out for asymptote and Geogebra; by the way, what kind of (latex?) commands do I need to plot the contour (basically a straight line on the complex plane which undergoes a square root transformation)?

Thanks a lot!
