The MathWorks has released MATLAB 7. This major new release of its flagship platform enhances programmer productivity with new tools that enable rapid, iterative program creation, says the company. In addition, it offers built-in support for integer and single-precision floating-point math, as well as language features for managing and analysing larger data sets. A large number of optimisations across data types, operations, functions, and hardware result in improved computational performance of end-user applications. Also new in the MATLAB family of products is an enhanced MATLAB Compiler that now supports the full MATLAB language, enabling developers to deploy many more MATLAB applications for use outside of MATLAB.
Among its new programmer productivity capabilities, MATLAB 7 features a redesigned desktop that includes new programming and debugging tools, automated program analysis for code quality, and publishing of code and output directly to HTML and Word. New interactive point-and-click plotting tools enable faster and easier creation of MATLAB graphics, including the ability to generate code that recreates plotting sessions for later use or redistribution.
Adding to its robust support for double-precision mathematics, MATLAB now supports integer and single-precision data types and arithmetic. Operating on data as integers or single-precision values instead of double-precision values offers significant savings in performance and storage, thereby enabling users to work with larger data sets, according to the company. This capability, combined with the incorporation of new FFT algorithms, is claimed to enable MATLAB users to perform a single-precision FFT 20% faster on average. Also, MATLAB now takes advantage of the Intel MMX library, resulting in up to eight times speed up for computations on integer data.
