In MATLAB, an array is a data structure used to store elements in contiguous memory blocks. A column vector is a one−dimensional array of elements. In a column vector, the elements are arranged column−wise. It is also important to note that MATLAB by default stores arrays in a column wise manner which means the elements of the array are stored in the memory as a column vector. In this article, we will explore different approaches to convert an array into a column vector using MATLAB programming. Method (1): Using Transpose Function We can turn an array into a column vector ... Read More
R packages play an important role in enabling researchers, analysts, and developers to leverage the potential of machine learning in the dynamic field of data science. These programs offer a comprehensive collection of tools and functionalities that ease difficult data analysis processes, making them indispensable for industry experts. In this article, we will explore the top seven R packages for machine learning, their importance, and how to use them effectively. 7 Best R Packages for Machine Learning Below are the seven R packages for machine learning − Caret Caret is an R package that supports a wide range of machine-learning ...

In MATLAB, a matrix is nothing but an array of rows and columns arranged in a square or rectangular shape. A matrix is basically a two−dimensional array of numbers. MATLAB allows us to create various types of matrices, such as n × n matrix, n × m matrix, column vector, row vector, etc. In this article, we will learn how to turn a matrix into a row rector using MATLAB programming. A row vector is a one−dimensional array in which the elements of the matrix are arranged in a single row. When we create a row vector, MATLAB stores the ... Read More
In computer−based image analysis and processing, the image segmentation is an essential task. The image segmentation allows us to extract specific objects or regions from an image. In digital image processing, the most widely used image segmentation technique is the thresholding−based image segmentation. This image segmentation technique works depending on the pixel intensity values to separate different regions within an image. In this article, we will discuss learn the implementation of thresholding−based image segmentation using MATLAB programming. But before that let’s get into the basics of thresholding and its types. What is Thresholding? In digital image processing, the thresholding is ... Read More
In the field of digital image and video processing, there are two popular color spaces namely RGB and YIQ. Where, RGB stands for Red, Green, and Blue. The RGB color space is widely used for displaying digital images on display screens. This color space utilizes a combination of intensities of red, green, and blue lights. Therefore, in the RGB color space, each pixel in a digital image composed of three−color channels namely red, green, and blue. On the other hand, YIQ is another color space that is mainly employed in analog video or NTSC systems. YIQ stands for Luminance (Y), ... Read More
In this article, we will learn how to create a function in MATLAB and how to use that function in a MATLAB program to perform an operation. What is a Function in MATLAB? In MATLAB, a function is nothing but a block or set of instructions used to perform a specific operation. A function basically eliminates the need of writing instructions repeatedly. Also, it encapsulates all the technical information of the operations and provides a short and easy to use executable code to perform the operation. Functions has several advantages such as easy implementation, reusability, easy maintenance, etc. Components of ... Read More
In this article, we will learn how to create a dropdown menu/list in MATLAB. In MATLAB, a dropdown menu is a user interface (UI) component allows users to choose one the multiple options or to type as text. In MATLAB, we have a built−in function named ‘unidropdown’ that allows to create a dropdown menu. This function can have different syntaxes to create different types of dropdown menu. The most commonly used types of dropdown menu are as follows: Dropdown menu without any parameters Dropdown menu with a specific parent container Dropdown menu with a specific parent container and properties ...

In this article, we will learn to implement MATLAB codes to count the number of circles in a digital image. The counting the number of circles in an image is performed by using various image processing techniques like image erosion, circle detection, etc. The step−by−step procedure to count the number of circles in a digital image in MATLAB is explained below: Step (1)− Read the input image. Step (2)− Convert the input image to grayscale, if necessary. Step (3)− Create a circular or disk−shaped structuring element of a specific size for erosion of the image. Step (4)− Erode the grayscale ... Read More
In this article, we will discuss how to convert an RGB image into an HSI (HSV) image using MATLAB. The RGB color space is widely used for displaying digital images on display screens. This color space utilizes a combination of intensities of red, green, and blue lights. Therefore, in the RGB color space, each pixel in a digital image composed of three−color channels namely red, green, and blue. On the other hand, HSI stands for Hue Saturation and Intensity. It is also called HSV, where HSV stands for Hue Saturation Value. An image represented based on the color model of ... Read More
In MATLAB App environment, we can develop a GUI (Graphical User Interface) app without having proper knowledge of coding. Therefore, MATLAB app building allows us to create professional applications without writing code, and just by drag−drop. In this article, we will discuss how to create a GUI button in a MATLAB application. The step−by−step procedure to create a GUI button in a MATLAB app is explained below. Steps to Create GUI Button in MATLAB App We can follow the following steps to create a GUI button in a MATLAB application: Step(1)– Open the MATLAB command window. Step(2)– Launch the MATLAB ...
