Root Mean Square Error (RMSE) is an error estimation technique used to calculate the difference between estimated values and actual values. This method provides the average value of errors as a single value. We can use MATLAB to calculate the root mean square error. For this, MATLAB provides various built-in functions. In this tutorial, I will explain how to calculate the Root Mean Square Error (RMSE) in MATLAB. What is Root Mean Square Error (RMSE)? The root mean square error (RMSE) is a method of measuring error or accuracy of a predictive tool or model. It is calculated by finding ... Read More
Reduced row echelon form (rref) matrix is a simplified matrix used to solve a system of linear equations. MATLAB provides some built-in functions to find the reduced row echelon form matrix of a given matrix. Read this article to learn these methods of finding the reduced row echelon form matrix of a given matrix using MATLAB. Before that let’s get an overview of rref matrix and its properties. What is a Reduced Row Echelon Form Matrix? In linear algebra, the reduced row echelon form matrix, also known as rref matrix, is a special and simplified matrix used to solve systems ... Read More
When we multiply two N-dimensional matrices along each dimension or page of the two matrices, then it is called page-wise matrix multiplication. Page-wise matrix multiplication is mainly performed in the case of 3-dimensional matrices. Go through this tutorial to learn the methods of performing page-wise matrix multiplication using MATLAB. What is Page-Wise Matrix Multiplication? When two N-dimensional matrices are multiplied along each dimension of the two matrices, then this type of matrix multiplication is called the page-wise matrix multiplication. It is basically the element wise multiplication of two 3D matrices along a specific dimension or page in a 3D matrix. ... Read More
An Auxiliary memory is referred to as the lowest-cost, highest-space, and slowest-approach storage in a computer system. It is where programs and information are preserved for long-term storage or when not in direct use. The most typical auxiliary memory devices used in computer systems are magnetic disks and tapes.Magnetic DisksA magnetic disk is a round plate generated of metal or plastic coated with magnetized material. There are both sides of the disk are used and multiple disks can be stacked on one spindle with read/write heads accessible on each surface.All disks revolve together at high speed and are not stopped ...

Server−side rendering has been around for a while now. It was first introduced in the early 2000s and has been used by many websites since then. The idea behind this technique is to pre−render HTML pages on a server and send them back to the client's browser as they request them. With server-side rendering (SSR), the page is rendered on the server. This ensures that the page is available to users even before it loads on their browser. We’ll get to know more about SSR in this article − How Server-side Rendering (SSR) Works? It is the process of rendering ... Read More
In this program we will see how to multiply two 8-bit numbers using 8085 microprocessor.Problem StatementWrite 8085 Assembly language program to multiply two 8-bit numbers stored in memory location and store the 16-bit results into the memory.DiscussionThe 8085 has no multiplication operation. To get the result of multiplication, we should use the repetitive addition method.After multiplying two 8-bit numbers it may generate 1-byte or 2-byte numbers, so we are using two registers to hold the result.We are saving the data at location 8000H and 8001H. The result is storing at location 8050H and 8051H.InputAddressData......8000DC8001AC......Flow DiagramProgramAddressHEX CodesLabelsMnemonicsCommentsF00021, 00, 80LXI H, 8000HLoad ... Read More
To add legends in a subplot, we can take the following Steps −Using numpy, create points for x, y1, y2 and y3.Create a figure and a set of subplots, using the subplots() method, considering 3 subplots.Plot the curve on all the subplots(3), with different labels, colors. To place the legend for each curve or subplot adding label.To activate label for each curve, use the legend() method.To display the figure, use the show() method.Exampleimport numpy as np from matplotlib import pyplot as plt plt.rcParams["figure.figsize"] = [7.50, 3.50] plt.rcParams["figure.autolayout"] = True x = np.linspace(-2, 2, 100) y1 = np.sin(x) y2 = np.cos(x) y3 ...

To easily display single and multiple variables in Python, use the print() statement. For multiple variables, use the comma operators. Variables are reserved memory locations to store values. It means that when you create a variable, you reserve some space in the memory. Based on the data type of a variable, the interpreter allocates memory and decides what can be stored in the reserved memory. Therefore, by assigning different data types to the variables, you can store integers, decimals or characters in these variables. Print Single Variable in Python To display a single variable, simply use the print() method − ... Read More
Tree in which each leaf node describes an operand & each interior node an operator. The syntax tree is shortened form of the Parse Tree.Example1 − Draw Syntax Tree for the string a + b ∗ c − d.Rules for constructing a syntax treeEach node in a syntax tree can be executed as data with multiple fields. In the node for an operator, one field recognizes the operator and the remaining field includes a pointer to the nodes for the operands. The operator is known as the label of the node. The following functions are used to create the nodes ... Read More
In C++ stream refers to the stream of characters that are transferred between the program thread and i/o.Stream classes in C++ are used to input and output operations on files and io devices. These classes have specific features and to handle input and output of the program.The iostream.h library holds all the stream classes in the C++ programming language.Let's see the hierarchy and learn about them, Now, let’s learn about the classes of the iostream library.ios class − This class is the base class for all stream classes. The streams can be input or output streams. This class defines members that ... Read More
