Hash tables are efficient data structures used to store key-value pairs, making them essential for various applications. Linear probing is a collision resolution technique that helps handle situations when two keys map to the same index in the hash table. In this article, we will explore the implementation of a Hash Table with Linear Probing in Golang, using arrays and maps, gaining insights into their workings and practical applications. In the below examples we are going to perform insertion and retrieval operations using a hash mechanism and collision resolution strategy. Explanation In the below example, keys [10 , 25, ...

A deque is a versatile data structure that allows insertion and deletion of elements from both ends efficiently. The doubly linked list provides an excellent foundation for building a deque as it allows easy traversal in both directions. In this article, we will explore deque using doubly linked lists in go with two methods: using a custom doubly linked list and using the built-in container/list package in Golang. Here in the below examples we will showcase the operations of a double ended queue, we will perform the insertion and deletion operations at both the ends. Explanation As you can see ... Read More

In digital image processing, there is a technique called histogram equalization which is used to enhance the visual quality of an image by manipulating contrast in the image. Histogram equalization improves the quality of an image by redistributing the pixel values across the entire image, so that the histogram of the image can be uniformly distributed. Histogram is nothing but the frequency of occurrence of each pixel intensity value. Sometimes, we see that the pixel intensities in an image are concentrated in a particular range and results in the poor visual quality of the image. Histogram equalization is used to ... Read More

In MATLAB, a denoising filter is a tool that can reduce or remove noise from a digital image or a digital signal. As we know, noise is an unwanted signal or disturbance in a digital signal that impacts the quality of the signal or can cause errors in the signal processing. Therefore, it is required to remove or reduce the noise in a signal or image. This can be done with the help of a denoising filter. In this tutorial, we will explore several different types of denoising filter in MATLAB and will implement them using MATLAB programming. Types of ... Read More

In mathematics, trapezoidal numerical integration is a method of approximating the definite integral of a function over a certain interval. In the trapezoidal numerical integration, a curve is divided into multiple trapezoids and then areas of all the trapezoids are calculated and added to estimate the total area under the curve. It is a basic method for approximating the definite integral of a function. Hence, it is not much accurate as the other advanced integration methods. However, for simple functions, this method can provide a reasonable approximation. Trapezoidal Numerical Integration Using MATLAB In MATLAB, we have a built-in function 'trapz' ... Read More

In MATLAB, we can create a video from a sequence of images. In this tutorial, we will explore the steps involved in creating a video from an image sequence and will take an example to understand the concept practically. Process of Creating Video From a Sequence of Images The step-by-step process of creating a video from a sequence of images is explained below − Step (1) − Firstly, collect all the images in a folder that we want to use in the video. Step (2) − Read all the images using the 'imread' function and store them in a ... Read More

In MATLAB, we have a built-in GUI App Designer environment that allows us to develop various types of GUI (Graphical User Interface) applications with proper knowledge of software engineering and programming. In this MATLAB’s app designer environment, we can create various kinds of GUI components such as TextFields, Buttons, NumEditFields, Labels, Hypertext, and more. In this tutorial, we will explore how to create a TextArea Component in MATLAB app. TextArea Component in MATLAB In MATLAB, the TextArea is a GUI component allows application users to input a string of text. MATLAB provides a built-in function ‘uitextarea’ to create a TextArea ... Read More

In MATLAB, a matrix is nothing but a 2D (two-dimensional) array of numbers arranged in multiple rows and columns. Matrix is the most elementary data structure in MATLAB programming which is utilized to store and manipulate data. In this tutorial, we will learn how to create a new matrix from all possible row combinations in MATLAB. For this, we can use MATLAB's built-in function 'randperm'. The 'randperm' function will randomly select a row index and create a new matrix. Algorithm The step-by-step process to create a new matrix from all possible row combinations is described below − Step (1) ... Read More

MATLAB is an efficient tool to create matrices. In MATLAB, a matrix is a two-dimensional array that can store data in the form of rows and columns. MATLAB allows us to create matrices by using nested loops. In this tutorial, we will learn how to create a matrix using a nested loop in MATLAB. In MATLAB, creating a matrix using nested loop is a straightforward two step process. The step-by-step process to create a matrix using a nested loop is explained below − Step (1) − Initialize the matrix and specify the loop limits depending on the number of ... Read More

In MATLAB, we can use the MATLAB's built-in GUI environment 'App Designer' to create a hyperlink component. The App Designer Environment of MATLAB allows to create several types of GUI components like hyperlink, buttons, sliders, text fields, etc. To create a hyperlink component in MATLAB, we can use a built-in option 'uihyperlink'. This function creates a GUI hyperlink component in MATLAB. This function allows users to navigate across web resources with a single click. The 'uihyperlink' function creates a hyperlink object in a MATLAB app. The 'uihyperlink' function can have the following syntaxes. (1). Create Hyperlink Object with Default Properties ... Read More
