They are available to download on the Linux, Windows, and Mac OS X operating systems. Octave, FreeMat, and Scilab are free numerical computational packages that have many of the same features as Matlab. Matlab is the most popular commercial package for numerical computations in mathematics, statistics, the sciences, engineering, and other fields. The assessment was made comparing the resultsĬomputed by the platforms with certified values, that is, known results,Ĭomputing the number of correct significant digits. Which includes the computation of basic univariate statistics (mean, standardĭeviation and first-lag correlation), linear regression and extremes of Provided by NIST (National Institute of Standards and Technology), a protocol Matrix determinants and eigenvalues, whose results are known. We propose a set of operations which include the computation of Verify the stability of the results with respect to small departures from the A Monte Carlo study was conducted in some of the datasets in order to Tests using standard data sets and using the functions provided by each Operating systems (Windows, Ubuntu and Mac OS). Modelling: MatLab, Octave and Scilab, running on i386 architecture and three In this article we test the accuracy of three platforms used in computational The overall performance of the freeware rival is very satisfactory, making it a good choice not only for educational use but also for scientific and professional purposes, especially when funding is critical. Although MATLAB outperforms Scilab in all the benchmarks except the disk file manipulations, in the presumed vectorization versions of the benchmarks, it is not for much. They include basic algebra and matrix calculations, signal generation, signal analysis, and storing and retrieving data to and from the hard disk drive. Their performance is tested by measuring the execution times of several combined-task benchmarks implemented as test functions, built upon nine common numerical tasks that are often found in programs for solving standard engineering problems. The motivation for the work emanated from the educational use of these tools at the college and university level, but with a perspective to their professional and scientific use as well.
#Scilab matrix software
In this paper, the authors compare the features and the overall performance of the two high-level numerical computing and modeling software environments: the freeware Scilab and commercially available industry-standard MATLAB.
