GLPK (GNU Linear Programming Kit) is intended for solving large-scale linear programming (LP), mixed integer programming (MIP), and other related problems. It is a set of routines written in ANSI C and organized in the form of a callable library.

This package contains some primary tools for evaluating sums, averages, integrals, derivatives, histograms/distributions of 1-d numerical data, and eventually for plotting the results. The stand-alone programs (supporting the standard UNIX input and output pipelines) are intended for data processing from the command line. They are especially useful for straightforward analysis of number series where a complex analytical approach is not necessary.
