Replace the Matrix Elements by Its Square in Java?
Matrices are nothing but it’s more than a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. As per the problem statement the task is replace the matrix elements by its square. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose the original matrix is {{8, 3, 2}, {12, 7, 9}, {6, 4, 10}}; After replacing the matrix element by its square, the result matrix will be 64 ...
Read MoreHow to Get File Owner’s Name in Java?
As per the problem statement, we are going to find the file owner name in Java. The owner’s name here represents the owner of the PC in which file is being runned. To find the file owner in Java we will use the getOwner() method of the FileOwnerAttributeView class. FileOwnerAttributeView belongs to the java.nio class. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose the given file location is “D:/saket.txt”. After checking for Owner name of the given file, the output will be − ...
Read MoreHow to Homogenize a Point in Java?
In this article we will see how to homogenize a point. Any point in the projective plane is represented by a triple (X, Y, Z), called homogeneous coordinates or projective coordinates of the point, where X, Y and Z are not all 0. The point represented by a given set of homogeneous coordinates is unchanged if the coordinates are multiplied by a common factor. As per the problem statement we have to homogenize a point by taking any common factor and multiplying it with the given points. Let’s start! To show you some instances Instance-1 Suppose the points are (10, ...
Read MoreHow to Find Single Digit Array Elements in Java?
In a given array with some random integer values, we have to find out the single digits available in the given array and print those single digit values as output. An array can contain positive or negative numbers irrespective of the number of digits in a number. As here all elements belong to numeric type. Note- Take a positive integer array. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Given Array= [1, 12, 3, 4, 10, 15]. The single digit elements present in the ...
Read MorePlotting stock charts in excel sheet using xlsxwriter module in python
Factors such as data analysis and growth rate monitoring are very important when it comes to plotting stock charts. For any business to flourish and expand, the right strategy is needed. These strategies are built on the back of a deep fundamental research. Python programming helps us to create and compare data which in turn can be used to study a business model. Python offers several methods and functions through which we can plot graphs, analyse growth and introspect the sudden changes. In this article we will be discussing about one such operation where we will plot a stock chart ...
Read MoreFind Number of Sorted Rows in a Matrix in Java?
Matrices are nothing but a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. As per the problem statement the task is to count all the rows in a matrix that are sorted either in strictly increasing order or in strictly decreasing order. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose the original matrix is{ { 5, 6, 7, 8 , ...
Read MoreFind Minimum Elements in Each Row of Matrix in Java?
In Java, Array is an object. It is a non-primitive data type which stores values of similar data type. The matrix in java is nothing but a multi-dimensional array which represents multiple rows and columns. As per the problem statement we have to find the minimum element present in every row of a given matrix of a multi-dimensional array. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose the original matrix is = { {2, 3, 11, 4, 6}, ...
Read MoreCheck if a Matrix is Involutory or not in Java?
Matrices are nothing but a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. Involutory matrix is a square matrix which when multiplied by itself, gives back an identity matrix. Identity matrix is a matrix in which all elements are zero except the diagonals which are one. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose we have a matrix | 1 0 ...
Read MoreHow to Check if the Matrix is a Magic Square in Java?
Matrices are nothing but a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. As per the problem statement the task is to check if the matrix is a magic square or not. A matrix is said to be a magic square if the sum of elements of any row, column or diagonal is equal to a specific number. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some instances Instance-1 Suppose ...
Read MoreCheck if a Matrix is Markov Matrix or not in Java
Matrices are nothing but it’s more than a collection of data elements arranged in a rectangular layout that is two-dimensional. In Java, an array with two dimensions can be considered as a matrix. A square matrix is called a Markov matrix if all entries are nonnegative and the sum of each column vector is equal to 1. The Markov matrix represents steps in a Markov chain. Each input of the Markov matrix represents the probability of an outcome. Let’s deep dive into this article, to know how it can be done by using Java programming language. To show you some ...
