MATLAB allows matrix manipulation, feature and data building, the introduction of algorithms, the creation of user interfaces, and interactions with programs written in other languages. Although MATLAB is primarily designed for numerical computing, an additional toolkit uses the MuPAD symbolic engine to access symbolic computing capabilities. An additional package, Simulink, adds a graphic lot of domain modeling and model design to dynamic and built-in systems. By 2020, MATLAB has more than 4 million users worldwide. MATLAB users are from various faculties of engineering, science and economics. The story of Clive Mohler, Chair of the Computer Science Department at the University of New Mexico, began developing MATLAB in the late 1970s. He soon expanded to other universities and found a strong audience in the applied mathematical community. Jack Little, an engineer, was exposed to this during Mohler's visit to Stanford University in 1983. Recognizing his commercial potential, he joined Moler and Steve Bangert. They rewrote MATLAB's C and founded MathWorks in 1984 to continue their development. These census libraries were known as JACKPAC. In 2000, MATLAB was rewritten to use a new set of libraries for matrix manipulation, LAPACK. MATLAB was first adopted by researchers and practitioners in engineering management, Little's specialty, but quickly spread to many other areas. It is now also used in education, in particular, the teaching of linear algebra and and is popular with scientists involved in image processing. The MATLAB Syntax App is built on matLAB programming language. The usual use of the MATLAB app involves using the Command Window as an interactive mathematical shell or executing text files containing the MATLAB code. Variable variables are defined by the destination operator. MATLAB is a poorly typed programming language because types are implicitly transformed. This is a deduced language because variables can be assigned without declaring their type, except when they should be considered as symbolic objects, and that their type may change. Values can come from constants, from calculations that include the values of other variables, or from the output of the function. For example: x 17 x 17 x 17 x x hat x x x zgt' zgt; x pi/2x y 12.0000 1.5708 q 3'sin (x) y -1.6097 3.0000 Vectors and Matrix Simple array is determined by colon syntax: initial:incre terminatorment: initial: incremental terminatorment. For example: The Array 1:2:9 Array 1 3 5 7 9 defines an array with a variable name (or assigns a new value to an existing variable with an array of names), which is an array of values 1, 3, 5, 7, and 9. That is, the array starts with 1 (initial value), increments with each step from the previous value to 2 (increment value), and stops as soon as it reaches (or to avoid exceeding) 9 (Terminator value). The increments value can actually be left out of this syntax (along with one of the colon) to use the default 1. 1:5 ari 1 2 3 4 5 assigns variable ari array with values 1, 2, 3, 4 and 5, as the default 1 is used as an increments. Indexing is based on a single basis, which is a normal convention for matrix in mathematics, as opposed to zero indexing commonly used in other programming languages such as C, C and Java. The matrix can be defined by separating the line elements with an empty space or comma and using a comma to stop each line. The list of items should be surrounded by brackets. Brackets are used to access items and subarrays (they are also used to refer to the function argument list). A no16 3 2 13; 5 10 11 8; 9 6 7 12; 4 15 14 1 a 16 3 2 13 5 10 11 8 9 9 12 15 14 1 qgt; a (2.3) ans 11 Index sets can be indicated by expressions such as 2:4, which is rated up to 2, 3, 4. For example, a sub-matrix, taken from lines 2-4 and columns 3-4, can be written as: qgt;'gt; a(2:4,3:4) ans 11 8 7 12 14 14 A square size identification matrix n can be generated using eye function, and a matrix of any size with zeros or with the help of zeros and functions, respectively. Eye (3.3) ans 1 0 0 0 0 0 0 0 0 1 qgt; zeros (2.3) ans 0 0 0 0 0 0 0 qgt; of them (2.3) ans 1 1 1 1 1 1 1 1 1 Transponation vector or matrix does or does the function of a trans-posing or or or adding dot-prime after the matrix (without a point, the Prime will perform conjuged transponders for complex arrays): A B A.', C - transposal (A) A - 1 2 B, 1 2 C - 1 2 qgt; D - 0 3 ; 1 5, D.' D - 0 3 1 5 ans 0 1 3 5 Most features take arrays as input and work on each item. For example, mod (2'J,n) will multiply each element in J by 2, and then reduce each element of modulo n. MATLAB includes standard loops and while, but (as in other similar applications such as R), using vectorized notation is recommended and often performed faster. The following code, taken from magic.m, creates a magic square M for the odd n values (MATLAB meshgrid function is used here to create square I and J matrix containing 1:n). (J,I) - grid (1:n); A - mod (I and J - (n No 3) / 2, n); B - mod (I q 2 - J - 2, n); M-n-a-a-a-in-a-in-a-in-a-a-a-1; MATLAB structures support the types of structured data. Because all the variables in MATLAB are arrays, a more appropriate name is a structured array where each array element has the same field names. In addition, MATLAB supports dynamic field name names (field views by name, field manipulation, etc.). When you create a MATLAB function, the file name should be the name of the first function in the file. Real feature names start with an alphabetical symbol and may contain letters, numbers, or underline. Variables and functions are sensitive to business. The MATLAB processing feature supports lambda calculus elements by typing functional pens or links to features that are implemented either in .m files or in anonymous functions. MATLAB classes and object-oriented programming supports object-oriented programming, including classes, inheritance, virtual submission, packages, aisle semantics, and semantics. However, the syntax and call conventions are very different from other languages. MATLAB has value classes and reference classes, depending on whether the class has a handle as a super-class (for class classes) or not (for value classes). The behavior of the method call differs between the classes of values and links. For example, calling an object of method.method.); can only change a member of an object if an object is an instance of a reference class, otherwise value class methods must return a new instance if they need to change the object. An example of a simple class is below. classdef Hi methods of greeting function (obj) disp ('Hello!') end end When put in a file called hello.m, it can be performed with the following commands: x and Hello (); >> x.greet(); Hello! MATLAB's graphic and graphic programming user interface has tightly integrated graphing features. The function section can be used to produce a graph of two x and y. code: x 0:pi/100:2'pi; y sin (x); (x); produces the following synus function: MATLAB maintains 3D graphics, as well as: X,Y and meshgrid (-10:0.25:10,-10:0.25:10); f sinc (sqrt ((X/pi);2(Y/pi));grid (X, Y,f); Axis (No-10 10 -10 -0.3) xylabel ('bfx') ylabel ('bfy')) zlabel ('b'f'f ('f' fsin( FFR) is hidden from 'X,Y' and meshgrid (-10:0.25:10,-10:0.25:10); f sinc (sqrt ((X/pi);2(Y/pi)); surfing (X,Y,f); Axis (No-10 10 -10 -0.3) xylabel ('bfx') ilabel ('bfy '') zlabel ('bfsinc) BFR)))))) This code creates a 3D frame frame of the two-dimensional abnormal sinc function: This code creates a superficial 3D section of the two-dimensional abnormal sinc function: MATLAB supports the development of UI GUI GUI applications. UIs can be created either software or through visual design environments such as GUIDE and App Designer. Interaction with other MATLAB languages may be called functions and routines written in C or Fortran programming languages. A wrapper function is created that allows you to transmit and return matLAB data types. MEX (MATLAB executables) files are dynamically downloadable object files created by compiling such features. Since 2014, a two-year interaction with Python has been added. Libraries written in Perl, Java, ActiveX, or .NET can be directly sourced from MATLAB, and many MATLAB libraries (such as XML or S'L support) are implemented as wrappers around Java or ActiveX libraries.

ISSN 2277-3169 Volume 6, Number 1 (2016), pp. 11-18 © Research India Publications http://www.ripublication.com Some Effective Methods for Teaching Mathematics Courses in Technological Universities Dr. D. S. Sankar Professor, School of Applied Sciences and Mathematics, Universiti Teknologi Brunei, Jalan Tungku Link, BE1410, Brunei Darussalam E-mail: [email protected] Dr. Rama Rao Karri Principal Lecturer, Petroleum and Chemical Engineering Programme Area, Faculty of Engineering, Universiti Teknologi Brunei, Jalan Tungku Link, Gadong BE1410, Brunei Darussalam E-mail: [email protected] Abstract This article discusses some effective and useful methods for teaching various mathematics topics to the students of undergraduate and post-graduate degree programmes in technological universities. These teaching methods not only equip the students to acquire knowledge and skills for solving real world problems efficiently, but also these methods enhance the teacher’s ability to demonstrate the mathematical concepts effectively along with suitable physical examples. The exposure to mathematical softwares like MATLAB, SCILAB, MATHEMATICA, etc not only increases the students confidential level to solve variety of typical problems which they come across in their respective disciplines of study, but also it enables them to visualize the surfaces of the functions of several variable. Peer learning, seminar based learning and project based learning are other methods of learning environment to the students which makes the students to learn mathematics by themselves. These are higher level learning methods which enhances the students understanding on the mathematical concepts and it enables them to take up research projects. It is noted that the teaching and learning of mathematics with the support of mathematical softwares is believed to be more effective when compared to the effects of other methods of teaching and learning of mathematics.

Show the basics of how to use R through the "notebook interface" of Sage. Begin discussing the possibility of deeper interaction between the two communities. Sage (www.sagemath.org) is a comprehensive mathematics software package, whose general goal is to create "a viable free open source alternative to Magma, Maple, Mathematica and Matlab." If this sounds ambitious, it is. Part of the key is broad but high-quality functionality (about which more in a moment). Sage has just about all of the usual functionality you associate with the various mathematics programs starting with "M". integrate(1/(1+x^2),x); show(integrate(1/(1+x^2),x,-1,1)) arctan(x) 1 Ù 2 Maxima gives good symbolic calculus functionality, and the matplotlib Python library gives nice graphics - all wrapped in a unified, easy-to-use interface. plot(1/(1+x^2),(x,-1,1),fill=True)+line([(- 1,pi/4),(1,pi/4),(1,0),(-1,0),(-1,pi/4)],color='red',linestyle="-- ") Sage is built on Python, so of course objects persist and we can access object-oriented methods. y = function('y',x) f = desolve(diff(y,x) - y, y, ics=[0,1]) plot(f,(x,-3,3)) http://localhost:8000/home/admin/109/print Page 1 of 9 useR! 2010 Sage-R Talk -- Sage 7/22/10 8:58 AM show(f.taylor(x,0,7)) 1 1 1 1 1 1 x7 + x6 + x5 + x4 + x3 + x2 + x + 1 5040 720 120 24 6 2 This function is, of course, f(x) = ex.
