Often, you need to measure the time your microcontroller takes to perform a particular task. You can use the millis() function of Arduino to measure the time. This function returns the number of milliseconds passed since your board started running the current program. Therefore, to calculate the time taken by an operation, you can call millis() before and after your operation, and take the difference of the two values.An example implementation is given below −Examplevoid setup() { // put your setup code here, to run once: Serial.begin(9600); long int t1 = millis(); task_whose_time_is_to_be_measured(); long int ...

Let us look at an example that creates a package called animals. It is a good practice to use names of packages with lower case letters to avoid any conflicts with the names of classes and interfaces.Following package example contains interface named animals −/* File name : Animal.java */ package animals; interface Animal { public void eat(); public void travel(); }Now, let us implement the above interface in the same package animals −package animals; /* File name : MammalInt.java */ public class MammalInt implements Animal { public void eat() { System.out.println("Mammal eats"); } ...

In ReactJS, we can set the state in the child component by passing the values as a prop of the child component. Sometimes, we require to set the state from the children component to the parent component in ReactJS. We can create a state handler function in the parent component and pass it as a prop of the child component. After that, we can use the child component function to set the parent component's state. In such a way, we can manage the state of the parent component from the child component. Set parent state from children component in functional ... Read More
In MATLAB, there are various types of operators used to perform different operations. Two such operators are "&" and "&&". The "&" and "&&" operators are the logical operators used to perform element wise logical AND operations. However, they are absolutely different from each other on the basis of their behavior. Read this article to understand the basics of "&" and "&&" operators in MATLAB along with their applications in MATLAB programming. What is & Operator in MATLAB? In MATLAB, the "&" operator is an element-wise operator used to perform logical AND operation between two arrays. If we use ... Read More
MATLAB is a powerful tool to perform various mathematical tasks such as performing operations, plotting charts and figures, manipulating matrices, and more. In digital mathematical tools like MATLAB, there is a typesetting system called "TeX" which is used to communicate and publish mathematical equations and structures. This typesetting system was developed by Donald Knuth. In this tutorial, I will explain the TeX system in LaTeX math mode and the use of TeX symbols in legends and labels in a plot or figure in MATLAB. What is TeX in MATLAB? TeX is a typesetting system used to publish mathematical equations and ... Read More
MATLAB provides various built-in functions that enable us to write data in the form of tables, matrices, cell arrays, etc. to an Excel file. Read this article to learn the process of writing data to Excel spreadsheets in MATLAB. The following are some commonly used methods to write data to excel spreadsheets using MATLAB − Using the "writetable" Function Using the "xlswrite" Function Using the "writematrix" Function Using the "writecell" Function Let us discuss each of these methods in detail with the help of examples. Using "writetable" Function in MATLAB In MATLAB, the "writetable" is a built-in function ... Read More
In MATLAB, the process of ensuring that a function is executed with the correct and expected input and output arguments is termed as validating the number of function arguments. Go through this tutorial to learn how you can validate the number of function arguments in MATLAB. Validate Number of Function Arguments in MATLAB In MATLAB, we can define functions that take a specific number of input and output arguments. We need to ensure that the functions use these input and output arguments properly and also detect errors if any. Therefore, MATLAB provides a way of validating the number of arguments ... Read More
In data visualization, the polar axes are used to represent data in polar coordinates. Polar axes provide a way of visualizing complex data in the form of polar plots. Read this article to learn the methods of changing the properties of polar axes to control their appearance and behavior. Before learning to customize the appearance and behavior of polar axes, let us see how to create a polar axes and polar plot in MATLAB. How to Create Polar Axes in MATLAB? In MATLAB, there is a built-in function named "polaraxes" used to create polar axes in MATLAB figures. Its syntax ... Read More
In MATLAB, when we define multiple methods or functions with the same name but a list of different input arguments in a class, it is known as function overloading. In MATLAB programming, the function overloading is a part of polymorphism. Where, the concept of polymorphism says that a single function can behave differently depending on the nature or type of input arguments provided. This article is primarily meant for explaining the concept of function overloading in class definitions in MATLAB programming. But before that let us learn a bit about overloading functions in class definitions in MATLAB. What is Overloading ... Read More
Nearest-neighbor interpolation algorithm is a simple interpolation method used to interpolate unknown values between data points. We can implement this algorithm in MATLAB programming. Read this article to learn how to implement the nearest-neighbor interpolation algorithm in MATLAB. Let us start our discussion with the basics of nearest-neighbor interpolation algorithm. What is Nearest-Neighbor Interpolation Algorithm? The nearest-neighbor interpolation algorithm is a simple method to estimate the unknown values between discrete data points. This algorithm is quite useful in various fields of engineering like image processing, signal processing, etc. The principle behind this algorithm is very simple, that is, it assigns ... Read More
