Top 15 MATLAB Uses 

Through MATLAB Commands Users can reap the benefits of the MATLAB environment for many applications across a vast range of domains. Let’s explore some MATLAB Uses:

Uses of MATLAB

Embedded systems

Computer systems, comprising hardware and software components, are purposefully designed to perform specific tasks and are commonly known as Embedded Systems. MATLAB operators, when integrated with Simulink, can be effectively utilized together for code generation, followed by the execution of that code on hardware platforms. Additionally, Polyspace, a dedicated code analysis tool, plays a crucial role in the design, coding, and verification of new embedded systems, covering the entire spectrum from prototyping to production. The seamless integration of these tools, along with the use of MATLAB operators, contributes to the efficiency and reliability of the embedded systems development process.

Developers can generate C, C++, Verilog, and CUDA in optimised forms. They can also use floating-point design tools to trade costs and performance. MATLAB projects provides the functionality of ‘in-the-loop' testing for verifying and profiling generated code. The popular open-source electronic platform, ‘Arduino’, can be used for prototyping purposes with the help of the add-ons of hardware support packages from MathWorks. 

Signal processing

The applications of signal processing developed in MATLAB demonstrate the usage of communication and signal processing systems. The systems are utilised through the DSP System Toolbox software. The software allows users to model their digital signal processing systems with the help of the Simulink environment. Further, it provides users with the required algorithms to design and simulate various signal processing systems.   

The products of the software make it easier for developers to use signal processing techniques to analyse time series or time-stamped data. Developers can also benefit from the unified workflow for developing embedded systems and streaming applications. Streaming can be done by virtualising the application from a virtual machine or a machine server.   

Signal processing applications generally demand efficient computational architectures, which must be capable of balancing the power, performance, and size of various audio codec filters. Furthermore, these filters are intended for implementing algorithms designed to compress and decompress digital audio data. The data is usually based on an audio file or the coding format for a streamed media file.   

Image processing

Developers can process images by managing the pixels in any image. The matrix values in the image pixels can be modified using mathematical techniques. The process generally involves the addition of two matrices, where a constant value is typically added to the RGB (Red, Green, Blue) values of each image pixel. The resultant image is the same size as the two combined images, with the addition of the pixels from each image. Every pixel’s intensity is represented by the pixel’s value stored in a matrix form in a computing system. For a more detailed exploration of image processing, including operations like Matlab Convolation for advanced pixel manipulation, MATLAB provides a powerful environment for developers to implement and experiment with such techniques.

Once the images are processed, they are generally taken in for being utilised in computer vision. Computer vision is a concept where the computer perceives any object, like the human eye. The technology is designed to comprehend and predict the visual output through applied algorithms. Algorithms are crucial for tasks like image processing and computer vision. Users can leverage the Advantages of MATLAB to analyse their images and build their algorithms.

Internet of Things (IoT)

The MATLAB environment, with Simulink, can guide developers to design, prototype, and deploy their IoT (Internet of Things) applications. Developers can work with projects in operations optimisation, supervisory control, and predictive maintenance. Here are some key functionalities available to developers in the domain of IoT using the environment: 

1) Developers can access and pre-process streamed and archived data through interfaces built into the software. This data can be processed to the cloud and relational and non-relational databases. Developers can also leverage protocols for data transmission, such as Representational State Transfer (REST), MQTT, and Open Platform Communications Unified Architecture (OPC UA). 

2) MATLAB lets its users rapidly design their custom IoT analytics and algorithms from a large collection of tested and pre-built functions. These functions are intended for many purposes, such as data cleaning, computer vision, machine, and Deep Learning and optimisation. Users can utilise the library functions, customise them or make their own. 

3) Developers can create models based on data and physics-based configurations to control and optimise the network of their connected entities.
