We see graphically how linear programming optimizes a linear objective function in which the variables must satisfy a set of simultaneous linear equations. From the graphical view of points, we take following examples of linear programming problems of two variables...Introduction to Linear Programming
Introduction The objective of a linear programming problem is to obtain an optimal solution. Linear programming problems deal with the problem of minimizing or maximizing a linear objective function in the presence of a system of linear inequalities. The linear...User De fined Function in MATLAB
A function is a collection of sequential statements that accepts an input argument from the user and provides output to the program. Functions allow us to program efficiently. It avoids rewriting the computer code for calculations that are performed frequently....Selection Statements and Loop Statements in MATLAB
If the expression is true, then the commands are executed, otherwise the program continues with the next command immediately beyond the end statement. The simplest form of if statements is if statement1 ; end If the condition is true, the statement1 is executed, but...format Command in MATLAB
format Command style changes the output display format in the Command Window to the format speci ed by style. For example: format long pi ans = 3.141592653589793 several numeric display of formats...Variable Precision in MATLAB
MATLAB uses floating-point arithmetic for its calculations. Using the Symbolic Math Toolbox, we can also do exact arithmetic with symbolic expressions. For example: x = cot(pi/2) Output: x = 6.1232 e-17 The value of x is in floating-point format that is...MATLAB SCRIPTS
A Script is nothing but, a computer program written in the language of MATLAB. It is stored in an M- file. It is saved with extension .m. We can display the contents of the script in the Command Window using the type command followed by file name without .m...Comments in MATLAB
Comments are an integral part of any programming language. Comments help to identify program purpose and explain the work of particular statements in a program. Comments also allow others to understand the code. Comments can be used as help for a program. Suppose, You...Size and end function in MATLAB
size() Function size() function returns two values specifying the number of rows and columns of any matrix. For example: >> A=[1 2 3 7 4; 4 5 8 4 -3; 0 5 9 0 -3; 2 1 7 3 0 ]; >> [m n]=size(A) m = 4 n = 5 end Function MATLAB provides a special function...Vectors and Matrices in MATLAB
A vector is a list of elements. Elements should be separated by comma or space for row vector and semicolon for column vector. For example: >> B = [5 6 7] B = 5 6 7 >> b= [23; 34; 12] b = 23 34 12 A matrix is a rectangular array of numbers. Row and column...Variables and Assignments in MATLAB
In MATLAB, we use the equal sign to assign values to a variable. For example: >> u = 9 u = 9 Henceforth, MATLAB always takes the value of the variable u as 9. For example: >> u*2 – 2*u + u ans = 9 Note that MATLAB never forgets used variables unless...Basic Operations in MATLAB
In the Command Window, we see: >>: This notation >> is called the prompt. In the Command Window, MATLAB can be used interactively. It means that MATLAB command or expression can be entered, and MATLAB immediately responds with the result. For example, this...MATLAB
Introduction MATLAB is a standard tool which has been included in introductory and advanced courses in applied mathematics, engineering, science and economics in many universities around the world. In industry, it is a tool of research, development, and analysis....Linear Equations
Consider linear equations in unknowns namely of as: Equivalently, Associated with this system of equations is the matrix: Consider the matrix We can apply elementary row operations in the matrix A to get the matrix in reduced form. An elementary row operation on...History of Linear Programming
We are presenting a theory whose official birth was at the heart of the twentieth century and in fact in the years right after the Second World War. However, all the readers are familiar with the method of Lagrange multipliers from Calculus, named after Joseph Louis...Support Vector Machine for Speech Recognition

The Finite Volume Method (FVM) is a numerical technique that transforms the partial differential equations representing conservation laws over differential volumes into discrete algebraic equations over finite volumes (or elements or cells). In a similar fashion to...MATLAB®/Simulink® Functions—An Overview
MATLAB® is a high-performance language for technical computing. It integrates computation, visualization, and programming in an easy-to-use environment where problem and solution are expressed in familiar mathematical notation. MATLAB is an interactive system whose...Getting into MATLAB
MATLAB is a mathematical and graphical software package with numerical, graphical, and programming capabilities. It includes an integrated development environment, as well as both procedural and object-oriented programming constructs. It has built-in functions to...step and impulse function in MATLAB
MATLAB provides built-in functions for unit step function u(t) and unit impulse function δ(t). The unit step function is called Heaviside or stepfun, while the impulse function is Dirac. Heaviside(t) is zero when t < 0, 1 for t > 0 and 0.5 for t =...Support Vector Machine
SVM classifier is one of the latest and most successful supervised learning classifiers and has been widely applied for image classification due to its efficiency. Using training labeled samples, a statistical model is constructed and then new samples can be...Sorting in MATLAB
Sorting is the process of putting a list in order-either descending (highest to lowest) or ascending (lowest to highest) order. For example, here is a list of n integers, visualized as a column vector. What is desired is to sort this in ascending order in...Tables in MATLAB
A table is a data structure that stores information in a table format with rows and columns, each of which can be mnemonically labeled. For example, the following uses the table function to store some simple information for a doctor’s patients. >>names=...Advanced DATA Structures in MATLAB
MATLAB has several types of data structures in addition to the arrays, cell arrays, and structures that we have already seen. These can be found in the documentation under data types. Categorical Arrays Categorical arrays are a type of array that allows one to store a...Using Objects with Graphics and Plot Properties
MATLAB uses graphics in all of its figures. All figures consist of objects, each of which is referenced using an object handle. In versions of MATLAB prior to version R2014b, the object handles were unique real numbers that were used to refer to the object. With the...Introduction to Object Oriented Programming in MATLAB
Most programming languages are either procedural or object-oriented. Procedural programs are comprised of functions, each of which performs a task. Object-oriented programs use classes, which contain both data and functions to manipulate the data. Hybrid languages can...Sound Files in MATLAB
A sound wave is an example of a continuous signal that can be sampled to result in a discrete signal. In this case, sound waves traveling through the air are recorded as a set of measurements that can then be used to reconstruct the original sound signal, as closely...Introduction to App Designer
