What is MATLAB?

MATLAB is a high-level programming language specially developed for engineering and scientist to work on computational mathematics. It was developed by Cleve Molar of MathWorks.Inc company in 1984. It stands for Matrix Laboratory and allows the users to perform several activities, including matrix manipulation, plotting of functions, implementation of algorithms, etc. MATLAB is considered the combination of matrix and array mathematics with interactive and iterative processes and analysis.

Most companies have to waste their time, money, and effort to perform any operation or analysis based on complex calculations. They have to hire a separate team of experts for certain operations to run their business better based on useful information. However, this single MATLAB simplifies their work by providing amazing features and ease of performing complex tasks. Don’t even require a team for it.

It provides the programming environment which enables the computation of statements in the command window itself. The MATLAB programs can be written using:

• Command Window: This allows the execution of only a single statement at a time. The command window is used for simple calculations by engineers. It provides a greater command of the tools.
• Editor: This is used to run multiple lines at a time. This is the main window to load, run, edit and save the entire MATLAB program. It also provides the option of menu command consisting of the debug and run option of the program.
• Vector Operations:  It enables the users to perform several operations like addition, subtraction, and so on. It lets the user execute the program using a single command instead of multiple loops.

Top ideas and projects topics in MATLAB:

MATLAB is an automation tool that can generate certificates for workshops, conferences, symposiums, etc., and analysis reports for the massive data in big companies and organizations.

1. Automatic certificate generation in MATLAB:  Generation of the certificate automatically is the most significant and amazing method using which the certificates can be generated easily with less effort and time. Certificates are the proofs of your actions and encouragement of the students. The MATLAB enables the institutions to manage their work of generating the certificates in a better way. Almost all of the institutions and companies certifiers their trainee and students. However, creating certificates in large amounts is seems challenging for the organizations after having a large number of certificate receivers. MATLAB provides the opportunity to generate the certificate automatically in multiple amounts and saves time and effort. By using MATLAB, the students or the users don’t have to worry about the loss of certificates because they can access their certificates anytime from anywhere.

Here is an overview of the automatic certificate generation project.

• Firstly the name of the blank certificate will be used as an input into the code.
• Then the certificate details will be imported from the excel sheet and written on the blank certificate.
• Now the MATLAB source code will generate many such certificates automatically.
• Since the certificates have been generated automatically, they can be saved in any folder with a unique file name.

2. Image processing using MATLAB: Image processing is the method of transforming the normal image into the digital image using MATLAB tools and performing different calculations on it to extract useful data.

All the performed operations are based on a designed algorithm, so the chances of error are reduced here. The need for image processing is in almost all the fields involving medical, military, consumer electronics, etc.; in the military, it is used for analyzing the vehicles of soldiers, missile guidelines, and so on. Complex image processing algorithms are used in medical sectors such as radiography, positron emission tomography, etc.

• Image processing is highly used in digital cameras, high-definition TVs, DVD players, and other common electronics items. The image processing

Here are basic steps involved in image processing:

1. Analyzing the image
2. Manipulating the image includes operations like data compression, image enhancement, and filtering.
3. Generating the desired image as output.

Digital image processing in MATLAB can be used to get the following objectives:

1. Conversion of signals from the image sensor to digital sensors
2. Getting the scale and size of the objects in any scene.
3. Enhancing the image quality for printing and display.
4. Compressing the images for the communication over networks.

3. Use Artificial Neural Network for Image Encryption: Encryption converts plain text into ciphertext using a key. This key can be a private key or a public key. Encryption of images is required to keep the image safe from unauthorized access or get in hands of the wrong person. An artificial neural network is a system interconnecting the nodes or neurons in a layered structure. It can be used to recognize the patterns in images, classify the data, and forecast future events. The artificial neural networks in image encryption are used to find the approach and determine the signals, vision, and control system.

The artificial neural networks in image encryption are matter to segmenting images, detecting objects in images that can be useful, and much more. If any person is interested in cyber-security and cryptography then it can build this interesting project on MATLAB. The user can encrypt the image at the end by using an artificial neural network and this artificial neural network can again be used to decrypt the image and extract the useful information sent by the sender without involving the third party in it. The image encryption using the artificial neural network completely restricts unauthorized actions such as viewing the image, accessing the image, pulling the hidden information into it, etc. it is a simple and secure method to hide information from the unwanted user.

Here is the workflow for building the neural network in MATLAB:

1. Data preparation:
2. Modeling:
3. Simulation and Test
4. Deployment.

4. Design and apply an electronic differential system: The electronic differential system is used in vehicles to enhance the balance factor and provide better stability while turning at a curved path. The MATLAB enables the users to implement and design this differential system without having complexity in understanding the designs, diagrams, and its components. The manufacturers use the electronic differential system instead of mechanical differential because the mechanical counterparts are not able to provide advantages like electronic differential system. This system provides enough torque to the wheels that are required by the wheels on the turning path. Since the inner wheels have less radius than the outer wheel has, the rotation speed is also different.

And to get the necessary torque for the wheels, the electronic differential system uses the signal of motor speed and steering wheel command to better balance the wheels on the turning points of the path. The tractional optional is one the most required for wheels that do not restrict the torque. However, the torque is unavailable in many systems, and this can be one reason why the engineers prefer the electronic differential system much than the mechanical differential system.

5. Create Light Animations with MATLAB and Arduino: Light animation project includes the objective of controlling the light patterns of more than one light by creating a graphical user interface (GUI) and Arduino. The Arduino is a hardware open-source programming platform. The user embedded the coding and the algorithms for the project in the Arduino UNO board. This project is for beginners who are not very expert in using MATLAB because this project will not require too much complex process. The graphical user interface allows the users to perform other tasks while running the animation. Now the question arises what is the need to control the light? So the answer is the user can create amazing and beautiful various light animations by controlling the light patterns.

The MATLAB tolls are very versatile and flexible for building any projects and us easy to learn for non-technical persons. Once you have built this light animation project, then you go take this project further and extend it by adding more lights and creating unbelievable animations to amaze your society. People can demand this project to have perfect customized light patterns without having any difficulty. It will enable the user to control the light patterns in just one click and access it from anywhere. By building the user interface simple and easy, this application can help people to better understand it. This brings user-friendly features to it. It will attract the customer and enhance user engagement in the business and let them experience perfect lighting.

Future scope of MATLAB

Well, the future scope of MATLAB is very vast. With the increasing dependency of people on a digital platform, the business and organization will require to use MATLAB for better research in programming, mathematics, or any other critical calculations. MATLAB is a high-performance tool and matrix laboratory, so it allows the users to manipulate the data, implement different algorithms, draw data, and visualize simply. Thus it has a very large future scope.
