      Objective

      The objective of this chapter is to introduce the fundamental description of MATLAB. This chapter also describes the MATLAB installation and the different characteristics of MATLAB.

      Introduction

      MATLAB stands for Matrix Laboratory; it is a high-level language. MATLAB is used for a computational point of view. When data is in a matrix or vector form, then it is easy to manipulate or compute efficiently. MATLAB provides various inbuilt functions and tools that are are very easy to work and adapt to your task. MATLAB allows matrix manipulation according to the task; it is a high-level language. MATLAB is also helpful for mathematical computations. Some mathematic calculations are Matrices and Arrays, Algebraic Equations, Non-linear Functions, Statistics, 2-D and 3-D Plotting and graphics, Linear Algebra, Calculus, and Differential Equations, Numerical Calculations, Integration, Transforms, Curve Fitting, Data Analysis, and so on.

      Importance of MATLAB

      These are various importance of MATLAB:

      Easy to numerical computation

      Processing of massive amount of data

      Representation and visualization of data

      User interactive environment

      Mathematical equations and computations

      Statistical measurement and computations

      Prove tools for creating applications

      Support other languages like C, Java, .Net, and so on.

      The MATLAB interface

      In a MATLAB interface, there are the following components such as MATLAB desktop, command window, MATLAB prompt, current directory pane, and so on. The MATLAB desktop contains various menus such as HOME, PLOTS, APPS, EDITOR, PUBLISH, and VIEW.

      The MATLAB desktop contains various sub-windows. This represents a complete description of MATLAB. In Figure 1.2, we quickly understand about MATLAB desktop.

      The Features of MATLAB

      These are the following features of MATLAB:

      Symbolic integration, differentiation, transforms, and linear algebra

      Algebraic and ordinary differential equation (ODE) solvers

      Simplification and manipulation of symbolic expressions

      Unit systems for specifying, converting, and computing using SI, US, and custom unit systems

      Plotting of analytical functions in 2D and 3D

      Symbolic expression conversion to MATLAB, Simulink, C, Fortran, and LaTeX

      Variable-precision arithmetic

      The MATLAB paradigm

      These are the following paradigm from understanding the necessary details of MATLAB. This is very important for various tasks performing on MATLAB. This paradigm is showing the different properties of MATLAB, such as Comment Window, Current Folder path, Editor, Command Window, and so on.

      Applications of MATLAB

      There are various applications of MATLAB. Some of them are listed as follows:

      Industries

      Banking

      Academic organizations

      Medical field

      Statistical field, and many more.

      The MATLAB setup

      The following are the steps to install the setup of MATLAB:

      Firstly, choose the clients-Windows such as XP-SP2/Vista/Windows 7/Windows 8, then download MATLAB setup from an official website. Choose win32.rar or win64.rar according to your system configuration. Follow these steps for setting up MATLAB.

      Start the installer.

      For Windows, double-clicking on setup.exe file

      Click on Install without using the Internet

      When it starts, the installer displays the following dialog box. Select the option mentioned above and click OK to proceed with the installation.

      File Installation Key: Enter your File Installation Key and click OK.

      Figure 1.5: MATLAB installation process

      Choose Installation Type: In the Installation Type dialog box, specify whether you want to perform a Typical or Custom installation and click Next.

      Figure 1.6: MATLAB installation process

      Specify installation folder: Specify the name of the folder where you want to install MathWorks products. Accept the default installation folder or click Browse to select a different one. If the folder doesn’t exist, the installer creates it.

      Figure 1.7: MATLAB installation process

      Specify Products to Install (Custom only): Leave it by default and Continue.

      Specify the location of the License File: Enter the full path of your license file in the text box (or drag and drop the file) and click Next.

      Specify Installation Options (Custom only): After selecting installation options, click Next to proceed with the installation.

      Figure 1.9: MATLAB installation process

      Confirm your choices and begin copying files: Before it begins copying files to your hard disk, the installer displays a summary of your installation choices. To change a setting, click Back. To proceed with the installation, click Install.

      Figure 1.10: MATLAB installation process

      As it copies files to your hard drive, the installer displays a status dialog box to show the progress of the installation.

      Complete the installation.

      Figure 1.11: MATLAB installation process

      Set Environment Variables

      Right-click on My Computer

      Select Properties | Advanced System Settings | Environment Variables | New and then fill the entries.

      Some helpful screenshots

      Here are a few screenshots which might help you understand better.

      Command window

      The Command window is the main window. When you want to create a variable or run any commands, then you have to write on the command window. It is for user writing programs. In Figure 1.12, we quickly understand about command window.

      Figure 1.12: Command window

      Current directory section

      The current directory section is located on the left side of the command window. We can see the file navigation. This directory is for the current work directory. Make sure that this is the directory where you want to work so that MATLAB has access to your files and where it can save your new files. In Figure 1.13, we quickly understand about current directory.

      Figure 1.13: Current directory

      Workspace section

      In this section, it shows lists of all variables that you have generated. It also shows the type and size of the variable. In Figure 1.14, we can easily understand about workplace
