R programming language
It is based upon S which was developed by John Chambers of Bell Laboratories and described in the paper "Evolution of the S Language"  . R is considered by its developers to be an implementation of S, with semantics derived from Scheme. The commercial implementation of S is S-PLUS  .
Comparison with other programs
Although R is mostly used by statisticans, and other people in need of statistics, it can also be used as a general matrix calculation toolbox such as MATLAB.
