Drawing complex integration contours

Click For Summary

Discussion Overview

The discussion centers around the tools and methods for drawing complex integration contours, particularly in the context of preparing lecture notes. Participants explore various software options and commands that could facilitate this task.

Discussion Character

  • Exploratory, Technical explanation, Homework-related

Main Points Raised

  • One participant suggests using Asymptote if TeX is available, or Geogebra if it is not.
  • Another participant proposes creating PostScript pictures, noting that only a few commands are needed to define complex contours.
  • A later reply inquires about specific LaTeX commands required to plot a contour that represents a straight line on the complex plane undergoing a square root transformation.

Areas of Agreement / Disagreement

Participants present multiple software options and approaches without reaching a consensus on a single preferred method.

Contextual Notes

There are no specific assumptions or limitations mentioned, but the discussion may depend on familiarity with LaTeX and the capabilities of the suggested software.

Who May Find This Useful

Individuals interested in complex analysis, mathematical visualization, or those preparing educational materials in mathematics or physics.

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!
