% HOWTO:
% you need to install octave (https://octave.org)
% then navigate to the directory containing fn_parse_autorate_log.m and either:
% run 'octave --gui' in a terminal and open the file and run it (recommended if you want/need to edit values)
% or run 'octave ./fn_parse_autorate_log.m' from the terminal
% the following will work on the console without requiring interaction
% octave -qf --eval 'fn_parse_autorate_log("./SCRATCH/cake-autorate.log.20221001_1724_RRUL_fast.com.log", "./outpug.tif", [10, 500], {"1.1.1.1"})'
% symbolically: octave -qf --eval 'fn_parse_autorate_log("path/to/the/log.file", "path/to/the/output/plot.format", [starttime endtime], {selected_reflector_subset})'
% supported formats for the optional second argument: pdf, png, tif.
% the optional third argument is the range to plot in seconds after log file start
% the fourth argument is a list of reflector IDs, only samples from any of the listed reflectors will be plotted, use [] to select all reflectors
% by default the code will open a file selection dialog which should be used to select a CAKE-autorate log file.
% TODO:
% add CDF plots for RTTs/OWDs per reflector for low and high achieved rate states
% the goal is to show low versus high load delay CDFs, but we do not really know about the relative load so
% this will only be a heuristic, albeit a useful one, hopefully.
% - add OWD/RTT plots for both load directions
% - report 95 and 99%-iles of lowest load conditions as output to help selecting delay thresholds
