algoplot: A script for comparing the growth of functions

Examples

Merge sort (O(n log n)) vs. bubble sort (O(n^2))

algoplot -o merge-vs-bubble.png 'x * log(x)' 'x**2'

Usage

• Run algoplot -h for specific options
• Use x instead of n when plotting functions

Installation

You need

• Gnuplot installed with the gnuplot command available on your $PATH. Ensure you have gnuplot-x11 installed for Debian/Ubuntu in order to plot non-ASCII graphics.
• Ruby (only tested with 1.9.3)

Once you have the prerequisites installed, simply run the following command from your terminal:

gem install algoplot

You may need to prefix it with sudo depending on your setup.
