Hi, I'm Anatole V [Anatoly E. Voevudko, PhD], residing in the USA. My 1K bigger user page easy to find on OEIS Wiki. I was starting programming in the machine code for mainframe IBM 370. In last 2 decades I've created more then 30 websites (partially or in full). In addition, I've always been a scientist interested in AI. NT, etc. I've already contributed here on RC more than 90 solutions.

My Rosettacode Wiki Solutions

Fractals, trees and other plotting

Polyspiral in PARI/GP RC page

Plotting helper functions
• Plot the line from x1,y1 to x2,y2.
• Convert Polar coordinates to Cartesian.

Brownian tree RC page

Plotting helper functions
• Check if x,y are inside matrix mat[x,y]] (+/- p levels deep).
• Simple plotting using a square matrix mat (filled with 0/1).
• Writing file fn containing X,Y coordinates from matrix mat.
• Plotting from a file written by the wrtmat().
Brownian tree in PARI/GP versions #1 - #4
• Version #1. Translated from AutoHotkey.
• Version #2. Translated from Octave.
• Version #3. Translated from Seed7.
• Version #4. Translated from PureBasic.

Brownian tree in gnuplot RC page

Plotting helper file for load command
• Plotting from any data-file with 2 columns (space delimited), and writing to png-file.

Brownian tree in R RC page

Plotting helper functions
• plotmat(): Simple plotting using a square matrix mat (filled with 0/1).
• plotv2(): Simple plotting using 2 vectors (dumped into ".dmp" file by plotmat()).
