- In sci.math, a question was asked about taking the derivative of a non-
- analytic complex function. In particular, the poster was trying to
- differentiate
-
- f(z) = y + ix, where z = x + iy.
-
- My question is this: For such functions, is there any such point that
- corresponds to a critical point for analytic functions? I'm curious
- because I'd like to generate Mandelbrot-type sets for some functions of
- this nature, and I wonder where one would begin iterating. (For analytic
- functions, Mandelbrot images are generated by beginning the iteration
- at a critical point.)
-
- Thanks for any info,
- Kerry Mitchell
