Version 7.0 extends GAUSS with more than 30 new functions.
Aptech Systems (Maple Valley, WA) has released version 7.0 of its GAUSS mathematical and statistical modeling and analysis system, a fast matrix programming language designed for computationally intensive tasks. GAUSS is suitable for analysts, engineers, scientists, and researchers who do not have the time required to develop programs in C or FORTRAN or who find that most statistical or mathematical applications lack the flexibility or power to perform complicated, large-scale analysis problems.
Aptech has advanced the core functionality within GAUSS with a variety of new and improved statistical, mathematical, and matrix handling routines. In total more, than 30 new functions have been added, pushing the total number of built-in math functions to more than 400, including LINPACK, EISPACK and BLAS routines as well as factorizations, decompositions, eigenvalues, and distributions.
Among the key performance enhancements in version 7.0 are Structure Pointers. Structure Pointers allow you to avoid unnecessary data copying when passing structures in and out of procedures, making it possible to write faster programs. A new data set type, GAUSS Data Archives, holds multiple matrices, N-dimensional arrays, strings, and string arrays.
New functions in GAUSS 7.0 include a numerical integration procedure for integrals over infinite intervals and new multivariate normal and student’s t cumulative distribution functions. Also provided are three new thread-safe functions and five new functions for creating and opening data files.
Also, GAUSS 7.0 now supports multiple library paths and files larger than 2GB. Its documentation has been redesigned. Graphing options available include 2D, 3D, surface, contour, polar and log graphs, as well as bar graphs, histograms, and box graphs.
GAUSS 7.0, available now, runs on Windows, Linux, Mac, Solaris, and other platforms. For more, click here to go to the Aptech Systems website.
