Generates statistics of git repositories like http://gitstats.sourceforge.net but with a more extendable and flexible backend system

simple multiplot interface to enhance the gnuplot gem

Plot with ncl via Ruby: requires NCL 6.* and CDO 1.5.*

This gem contains command-line utility for solving 0/1 knapsack problem using branch-and-bound method, dynamic programming, simple heuristic (weight/price) and fully polynomial time approximation scheme. It can measure CPU and wall-clock time spent by solving a problem, compute relative error of...

Roctave is an attempt to provide some Matlab / Gnu Octave functions in a Ruby gem to generate and analyze digital filters.

gnuplot wrapper for ruby, especially for plotting roc curves into svg files

scbi_cominer is a ruby gem to calculate some interesting regions and statistics from contigs

scbi_plot is a simplified wrapper to create plots with gnuplot.

Seqtrimnext is a plugin based system to preprocess and clean sequences from multiple NGS sequencing platforms

Takes data and outputs it to multiple formats and media using a simple plugin system

A library of signal processing methods and classes for resampling, frequency domain transform (FFT and DFT), windowing (Blackman, Hamming, etc.), FIR filtering (windowed sinc), interpolation (linear and polynomial), plotting data, waveform generation, and more!

A tool for experimenting with Support Vector Machines.

Accepts a single or multiple tcpsnitch JSON traces as argument and compute statistical information.

texlab a toolkit based on erb that for creating documents and doing calculations at the same time. It is capable to output the proper number of significant digits, generate tables and plots using gnuplot. It has a simple DSL.

single interface to line-plotting data in [] or NArray

Compute values that change with time (or some independent variable), using various transitions (immediate, linear, sigmoid) between values.

This gem provides parsers for some of input and output files for VASP. This will provide support command for computations.

Viiite brings tools to benchmark and analyze the complexity of your algorithms. It has been designed as an alternative to Benchmark that let your benchmarks evolve smoothly from simple measures to more complex infrastructures.
