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
In an image, brightness is an attribute that is interpreted by our eyes based on the amount of light reflected by different regions of the image. Brightness is related to the intensity of light in the image i.e., if an image has more light it will appear brighter. If the image has less light, it will appear as darker. Therefore, brightness influences the visual quality of an image. However, we have various tools like MATLAB to adjust the brightness of the image and enhance its visual quality. In a digital image, the brightness is a controlled by pixel values of ... Read More
In mathematics, the Fourier series up to "n" harmonics is a technique used to approximate a periodic function through the sum of sine and cosine functions. We can implement the Fourier series up to "n" harmonics in MATLAB programming. Before discussing this implementation, let us first get an overview of Fourier series up to "n" harmonics. What is Fourier Series up to "n" Harmonics? In mathematics, the Fourier series is a method of expressing a periodic function as a sum of sinusoidal functions (sine and cosine functions). The Fourier series up to "n" harmonics is a way of approximating a ... Read More
In linear algebra, there is a fundamental theorem caled Cayley-Hamilton’s Theorem that is used to establish a relation between a square matrix and its characteristic equation. Read this article to learn the implementation of the Cayley-Hamilton’s theorem in MATLAB programming. Let's start with an overview of Cayley-Hamilton’s theorem. What is Cayley-Hamilton’s Theorem? In linear algebra, the Cayley-Hamilton’s theorem is a fundamental theorem that is used to establish a relationship between a square matrix and its characteristic equation. In other words, according Cayley-Hamilton’s theorem, a square matrix must satisfy its own characteristic equation. Explanation Consider a square matrix A of the ... Read More
In MATLAB, there are two commonly used image processing techniques namely, "Laplacian Filter" and "High Boost Filtering" that are used to sharpen an image. The Laplacian filter is mathematical operator used to sharpen an image in digital image processing. While, the high boost filtering is an image sharpening technique in digital image processing. In this tutorial, I will explain the process of image sharpening using Laplacian filter and high boost filtering in MATLAB. Let’s start with the basic introduction of Laplacian filter and high boost filtering. What is Laplacian Filter in MATLAB? In MATLAB, the Laplacian filter is mathematical tool ... Read More
Library functions are built-in functions that are grouped together and placed in a common location called library. Each function here performs a specific operation. We can use this library functions to get the pre-defined output. All C standard library functions are declared by using many header files. These library functions are created at the time of designing the compilers. We include the header files in our C program by using #include. Whenever the program is run and executed, the related files are included in the C program. Header File Functions Some of the header file functions are as follows − ... Read More
Decision TableA Decision Table is a table that shows the relationship between inputs and rules, cases, and test conditions. It's a very useful tool for both complicated software testing and requirements management. The decision table allows testers to examine all conceivable combinations of requirements for testing and to immediately discover any circumstances that were overlooked. True(T) and False(F) values are used to signify the criteria.What is Decision Table Testing?Decision table testing is a type of software testing that examines how a system responds to various input combinations. This is a methodical methodology in which the various input combinations and the ... Read More
