Mathematica 9

Mathematica 9 features the Wolfram Predictive Interface, a suite of features that intelligently suggests what to try next based on sophisticated heuristics and data from millions of Wolfram|Alpha queries. Analysis and visualization of statistical data and social networks (e.g. for Facebook, Twitter) is fully integrated with existing capabilities, such as instant interactivity, computable documents and symbolic computation. Additional features include highly integrated units support, including free-form linguistic entry, conversions and dimensional consistency checking across graphics and numeric and symbolic calculations; data science, probability and statistics functionality, including survival and reliability analysis, Markov chains, queueing theory, time series and stochastic differential equations; R language fully integrated into workflow for seamless data and code exchange; 3-D volumetric image processing and out-of-core technology that scales up performance to very large 2-D and 3-D images and video; and integrated analog and digital signal processing.
