In MATLAB, there is a built-in function “fprintf()” that is used to write data to a text file. The best part of this function is that it writes formatted data to a text file exactly in the same way as specified. Syntax fprintf(fileID, FormateSpecifier, Variables); Format Specifiers in MATLAB The following table gives a list of different format specifiers used with the “fprintf()” function in MATLAB: S. No. Format Specifier Description 1. %d or ... Read More
Introduction to Trapezoidal Numerical Integration Trapezoidal numerical integration is a method used for finding the approximate value of a definite integral. It is also called as the trapezoidal rule. In the case of trapezoidal numerical integration method, we use trapezoids to calculate the area under a curve. In the trapezoidal rule, the total interval over which we want to integrate is divided into smaller subintervals. The area under the curve is then approximated in each subintervals by using trapezoids. After that the total area under the curve is estimated through the sum of the areas of sub-trapezoids. This ...

JRE stands for Java Runtime Environment. It is mainly a part of the Java Development Kit (JDK). It is free of cost so we can easily find it on any software to use in our program. It consists of a Java class library, specific tools and many more important tools. JRE can be implemented on any operating system and it works as an outer layer of the operating system. It also consists of Integration Libraries and base libraries such as Java Database Connectivity (JDBC), Java Naming and Directory Interface (JNDI), Java Management Extension (JMX), Java Native Interface (JNI), Java for ...

JAVA is a robust, portable and highly secured programming language created by James Gosling at a company named Sun Microsystems, Inc. in 1991. The official name of this is OAK, Sun Microsystems renamed it JAVA in 1995. This company was taken over by Oracle Corporation. It is an all-purpose programming language and it is also an object-oriented programming language. JAVA is a widely used programming language in modern days. It contains various safeguards intended to prevent crashes at the time of program running such as Collection of garbage- no invalid addresses, checking of array and string boundaries, there is no ...

Consider a text file containing a sentence “I Study MATLAB from Tutorials Point.” Now, we want to read these words of the text file in the reverse order, the result will be “Point Tutorials from MATLAB Study I.”. In this article, we will explore the implementation of MATLAB program to read words in a text file in reverse order. Algorithm: Read Words in a File in Reverse Order In MATLAB, we have to follow the following steps to read the words in a file in reverse order: Step 1 - Open the file for reading by calling the function ...

Introduction to Intensity Transformation in MATLAB In MATLAB, the intensity transformation operation on images is one of the most fundamental image processing technique. It is an image processing operation in which the results depend on the intensity of an image. In MATLAB, the intensity transformation operations on images are performed to correct, enhance, or manipulate the intensity of image pixels. We have various built-in MATLAB functions to perform intensity transformation operations on images. In this article, we will discuss some commonly used intensity transformation operations and will see how they can be implemented using MATLAB programming. Intensity ... Read More
MATLAB provides various built-in functions, such as xlim(), ylim(), and axis() that help us to adjust axis limits as per our requirements. In this tutorial, we will learn about adjusting axis limits of a plot in MATLAB. Functions to Set Axis Limits In MATLAB, there are three main functions widely used for adjusting axis limits of a plot. These functions are as follows: “xlim()” Function - The “xlim()” function is used to adjust X-axis limit of a plot in MATLAB. “ylim()” Function - The “ylim()” ... Read More
To apply custom axis tick values, MATLAB has two built-in functions “xticks()” and “yticks()”. Here, the “xticks()” function is used for customizing the tick values of X-axis in a MATLAB plot, while the “yticks()” function is used for setting custom tick values to Y-axis. Syntax xticks([custom_tick_values]); yticks([custom_tick_values]); The following MATLAB program demonstrate the use of “xticks()” and “yticks()” functions to create custom tick values for X-axis and Y-axis. Example % MATLAB program to specify custom axis tick values % Create a sample vector of data x = linspace(1, 5, 5); y = x.^2; % Plot the x ... Read More
Mockito is built for testing the unit, whereas Wiremock is built specifically for the integration testing. Mockito aids itself as “a mocking framework that tastes really great” whereas wiremock stimulates itself as “a simulator for HTTP-based APIs”. Both wiremock and mockito are the technologies used for testing that is widely used for unit and integration testing in natural world applications. Developers have to understand these two important terms and how they differ from each other to use them in an effective way. Therefore, we will cover the main difference between these two extensively used tools in this article. What ... Read More
The covid pandemic has impacted billions of life all over the world. The pandemic led to widespread concern among the people. Several applications were built to determine and get accurate information about the total number of deaths, recovered cases, confirmed cases, etc. Fetching and analyzing this information is important for developers when they want to make applications around the pandemic. In this article, we will understand how to get the statistical data of the COVID−19 case. Using APIs APIs(Application Programming Interfaces) are important in modern programming and software development. This enables the software applications to interact with each other. ... Read More
