|What is Complex Plot?
Complex Plot is a mathematical application used to plot images of complex-valued functions of a complex variable. The Complex Plot project history is a long one; the project has gone from simple Pascal routines to a full-featured application. The software was developed by a number of students of Prof. Paul Bourdon at Washington and Lee University for use in his research on composition operators. The program (also known as Cplot) was written in C++ using the V GUI library, a cross-platform windowing library; click here for more information on Cplot's development and operation. In short, Cplot is a menu-driven application that plots complex-valued functions on a 2-D canvas.
Why Complex Plot?
Complex Plot was developed because the two major mathematical software packages, Waterloo's Maple V and Wolfram's Mathematica do not include routines to plot images of certain intertwining maps such as Koenigs eigenfunctions; moreover, when Maple and Mathematica are programmed to compute intertwining-map images, execution of the resulting code is painfully slow. Enter Cplot, which plots function and intertwining map images currently at rates up to 500% faster than Maple.
All of the example images were created using Cplot under varying plotting parameters.
