  • A Comparative Evaluation of Matlab, Octave, R, and Julia on Maya 1 Introduction
    A Comparative Evaluation of Matlab, Octave, R, and Julia on Maya Sai K. Popuri and Matthias K. Gobbert* Department of Mathematics and Statistics, University of Maryland, Baltimore County *Corresponding author: [email protected], www.umbc.edu/~gobbert Technical Report HPCF{2017{3, hpcf.umbc.edu > Publications Abstract Matlab is the most popular commercial package for numerical computations in mathematics, statistics, the sciences, engineering, and other fields. Octave is a freely available software used for numerical computing. R is a popular open source freely available software often used for statistical analysis and computing. Julia is a recent open source freely available high-level programming language with a sophisticated com- piler for high-performance numerical and statistical computing. They are all available to download on the Linux, Windows, and Mac OS X operating systems. We investigate whether the three freely available software are viable alternatives to Matlab for uses in research and teaching. We compare the results on part of the equipment of the cluster maya in the UMBC High Performance Computing Facility. The equipment has 72 nodes, each with two Intel E5-2650v2 Ivy Bridge (2.6 GHz, 20 MB cache) proces- sors with 8 cores per CPU, for a total of 16 cores per node. All nodes have 64 GB of main memory and are connected by a quad-data rate InfiniBand interconnect. The tests focused on usability lead us to conclude that Octave is the most compatible with Matlab, since it uses the same syntax and has the native capability of running m-files. R was hampered by somewhat different syntax or function names and some missing functions.

  • Ordinary Differential Equations (ODE) Using Euler's Technique And
    Mathematical Models and Methods in Modern Science Ordinary Differential Equations (ODE) using Euler’s Technique and SCILAB Programming ZULZAMRI SALLEH Applied Sciences and Advance Technology Universiti Kuala Lumpur Malaysian Institute of Marine Engineering Technology Bandar Teknologi Maritim Jalan Pantai Remis 32200 Lumut, Perak MALAYSIA [email protected] http://www.mimet.edu.my Abstract: - Mathematics is very important for the engineering and scientist but to make understand the mathematics is very difficult if without proper tools and suitable measurement. A numerical method is one of the algorithms which involved with computer programming. In this paper, Scilab is used to carter the problems related the mathematical models such as Matrices, operation with ODE’s and solving the Integration. It remains true that solutions of the vast majority of first order initial value problems cannot be found by analytical means. Therefore, it is important to be able to approach the problem in other ways. Today there are numerous methods that produce numerical approximations to solutions of differential equations. Here, we introduce the oldest and simplest such method, originated by Euler about 1768. It is called the tangent line method or the Euler method. It uses a fixed step size h and generates the approximate solution. The purpose of this paper is to show the details of implementing of Euler’s method and made comparison between modify Euler’s and exact value by integration solution, as well as solve the ODE’s use built-in functions available in Scilab programming. Key-Words: - Numerical Methods, Scilab programming, Euler methods, Ordinary Differential Equation. 1 Introduction availability of digital computers has led to a Numerical methods are techniques by which veritable explosion in the use and development of mathematical problems are formulated so that they numerical methods [1].

  • Numerical Methods for Ordinary Differential Equations
    CHAPTER 1 Numerical Methods for Ordinary Differential Equations In this chapter we discuss numerical method for ODE . We will discuss the two basic methods, Euler’s Method and Runge-Kutta Method. 1. Numerical Algorithm and Programming in Mathcad 1.1. Numerical Algorithm. If you look at dictionary, you will the following definition for algorithm, 1. a set of rules for solving a problem in a finite number of steps; 2. a sequence of steps designed for programming a computer to solve a specific problem. A numerical algorithm is a set of rules for solving a problem in finite number of steps that can be easily implemented in computer using any programming language. The following is an algorithm for compute the root of f(x) = 0; Input f, a, N and tol . Output: the approximate solution to f(x) = 0 with initial guess a or failure message. ² Step One: Set x = a ² Step Two: For i=0 to N do Step Three - Four f(x) Step Three: Compute x = x ¡ f 0(x) Step Four: If f(x) · tol return x ² Step Five return ”failure”. In analogy, a numerical algorithm is like a cook recipe that specify the input — cooking material, the output—the cooking product, and steps of carrying computation — cooking steps. In an algorithm, you will see loops (for, while), decision making statements(if, then, else(otherwise)) and return statements. ² for loop: Typically used when specific number of steps need to be carried out. You can break a for loop with return or break statement. 1 2 1. NUMERICAL METHODS FOR ORDINARY DIFFERENTIAL EQUATIONS ² while loop: Typically used when unknown number of steps need to be carried out.

  • A Case Study in Fitting Area-Proportional Euler Diagrams with Ellipses Using Eulerr
    A Case Study in Fitting Area-Proportional Euler Diagrams with Ellipses using eulerr Johan Larsson and Peter Gustafsson Department of Statistics, School of Economics and Management, Lund University, Lund, Sweden [email protected] [email protected] Abstract. Euler diagrams are common and user-friendly visualizations for set relationships. Most Euler diagrams use circles, but circles do not always yield accurate diagrams. A promising alternative is ellipses, which, in theory, enable accurate diagrams for a wider range of input. Elliptical diagrams, however, have not yet been implemented for more than three sets or three-set diagrams where there are disjoint or subset relationships. The aim of this paper is to present eulerr: a software package for elliptical Euler diagrams for, in theory, any number of sets. It fits Euler diagrams using numerical optimization and exact-area algorithms through a two-step procedure, first generating an initial layout using pairwise relationships and then finalizing this layout using all set relationships. 1 Background The Euler diagram, first described by Leonard Euler in 1802 [1], is a generalization of the popular Venn diagram. Venn and Euler diagrams both visualize set relationships by mapping areas in the diagram to relationships in the data. They differ, however, in that Venn diagrams require all intersections to be present| even if they are empty|whilst Euler diagrams do not, which means that Euler diagrams lend themselves well to be area-proportional. Euler diagrams may be fashioned out of any closed shape, and have been implemented for triangles [2], rectangles [2], ellipses [3], smooth curves [4], poly- gons [2], and circles [5, 2].

  • MATHCAD's PROGRAM FUNCTION and APPLICATION in TEACHING of MATH
    MATHCAD'S PROGRAM FUNCTION and APPLICATION IN TEACHING OF MATH DE TING WU Depart of Math Morehouse College Atlanta, GA.30314, USA [email protected] 1. Introduction 1.1 About Mathcad Mathcad is one of popular computer algebra system (math software) in the world. Like other CAS's, it has the capabilities to perform algebraic operations, calculus operations and draw graph of 2 or 3 dimensions. We can use it to get numerical, symbolic and graphic solution of math problem. Besides above common capabilities, it has some feature: its words processor function is better than other CAS. This feature makes it look like a scientifical words processor and it easy to create a woksheet. Following current trend to add program function to math software, it added program function to itself , started in Mathcad V7. This improvement makes its function more complete and more powerful. 1.2 Role of program function in teac hing of Math. Without doubt, math softwares and technology are helpful aide in teaching of Math. They are effecting the teaching of Math profoundly and it can be expected the emerging newer technologies will penetrate and reconfigure the teaching of Math. The program function is a new function of math software. It is natural we want to know whether or not it is useful in teaching of Math? I think: although for most problems we meet in teaching of Math it is enough to use computation ability, in certain cases the program function becomes necessary and very helpful. For example, for Numerical Analysis the program function is very useful but for Abstract Algebra it is less necessary.

  • Sageko Matlabin Korvaaja?
    Mikko Moilanen Sageko Matlabin korvaaja? Opinnäytetyö Tietotekniikan koulutusohjelma Elokuu 2012 KUVAILULEHTI Opinnäytetyön päivämäärä 4.9.2012 Tekijä(t) Koulutusohjelma ja suuntautuminen Mikko Moilanen Tietotekniikan koulutusohjelma Nimeke Sageko Matlabin korvaaja? Tiivistelmä Tässä insinöörityössä tutkitaan voiko Sagella korvata Matlabin korkeakouluopinnoissa matemaattisen analyysin opiskelutyövälineenä. Tutkimuksen perusteella arvioidaan, että onko Sagella tulevaisuutta ohjelmistona, varmistetaan Sagen toimivuus matemaattisessa analyysissa ja selvitetään, että miten helppoa yksittäisen käyttäjän on ottaa Sage käyttöön ja miten oppilaitos saa Sagen käyttöönsä. Matlab on kiistaton standardiohjelmisto matemaattisessa mallinnuksessa ja analyysissa. Sen peruslisenssimaksut ja Toolboxien lisenssimaksut ovat kuitenkin kohonneet ehkä juuri tästä syystä korkeiksi ja mikään ei estä lisenssimaksujen jatkuvaa kohoamista. Näin ollen halvemman vaihtoehdon löytäminen Matlabille korkeakouluopintojen työvälineenä on mielenkiintoinen ja hyödyllinen tutkimuskohde. Eräs mielenkiintoinen vaihtoehto Matlabille on Sage, koska se kokoaa lähes 100 matemaattista laskentaohjelmistoa yhden ja saman käyttöliittymän alle. Sage on myös suunniteltu toimimaan palvelin/asiakas -mallilla WWW-selaimella, mistä voi olla erityistä hyötyä laajoissa asennuksissa ylläpidon ja luokkahuoneidan varaamisen kannalta . Tutkimuksen tuloksena havaittiin Sagen olevan niin erilainen ja epäyhteensopiva Matlabin kanssa, että Matlab ei ole suoraan korvattavissa Sagella. Sen sijaan todettiin,
