A square matrix, one with exactly as many rows as columns, can represent a linear transformation of a geometric object. Applied Mathematics is future classified as vector algebra, differential calculus, integration, discrete Mathematics, Matrices & determinant etc. In video gaming industry, matrices are major mathematic tools to construct and manipulate a realistic animation of a polygonal figure. Let us suppose that we have two matrices namely A and B. Example 1. Know the Difference Between Cold, Flu, and H1N1. One of the uses of matrices is to represent linear transformations, which are higher dimensional analogs of linear functions where matrix multiplication corresponds to composition of linear transformation which is used in computer graphics to project 3- dimensional space onto a 2- dimensional screen. Let’s start with computer graphics, then touch on science, and return to mathematics. The field of probability and statistics may use matrix representations. Historically, the early emphasis was on the determinant, not the matrix. Another important task in matrix arithmetic is to calculate the determinant of a 2X2 square matrix. It causes absolutely no change as a linear transformation; much like multiplying an ordinary number by one. In an adjacency matrix, the integer values of each element indicates how many connections a particular node has. Suppose we have two square nXn matrices, A and B, such that AB=In. The evolution of the concept of matrices is the result of an attempt to obtain compact and simple methods of solving the system of linear equations. Chapter 5 contains matrix (operator) means for positive matrices. The numbers are called the elements, or entries, of the matrix. Matrices are used to model the wireless signals and to optimize them. Matrix mathematics applies to several branches of science, as well as different mathematical disciplines. The matrix given above has 2 rows and three columns. M is an mXn matrix; P is nXp; and the result R will have dimension mXp. 2.5: Application of Matrices in Cryptography 1. Matrices are key tools in linear algebra. It can be for an algorithm in programming, as basically a database, but often is used more for statistics regarding economics and mathematics. Advanced. Transformation matrices are commonly used in computer graphics and image processing. The points A,B,C are collinear if \[\begin{bmatrix} a  & b & 1\\ c  & d & 1 \\ e & f  & 1\end {bmatrix}\] vanishes. APPLICATION OF MATRICES IN CRYPTOGRAPHY. Let’s multiply matrices MP=R. Computers have embedded matrix arithmetic in graphic processing algorithms, especially to render reflection and refraction. There are a number of operations that can be applied to modify matrices, such as matrix addition, subtraction, and scalar multiplication. We can use matrices to find the area of any triangle where the vertices of the triangle have been given. However, few of us are likely to consciously apply matrix mathematics in our day to day lives. Pro Lite, Vedantu A probability vector lists the probabilities of different outcomes of one trial. Main problem in sensor array signal processing is to detect and locate the radiating sources given the temporal and spatial information collected from the sensors. A matrix organizes a group of numbers, or variables, with specific rules of arithmetic. There is much that we can do with matrices besides row operations: We can add, subtract, multiply, and even, in a sense, “divide” matrices. In mathematics, one application of matrix notation supports graph theory. 2.
