Question

write about daily uses of matrix?

Answer 1

✌️___________✌️

Any data that is organized in columns and rows can be represented as a matrix. Matrices are used to represent real-world data.
They are used in graphics and animation.
They are also used to solve systems of equations in many variables.
Matrices could be useful to figuring out things like price and quantity, like with the quantity foods and prices in our daily requirements.
Matrices can be used to encrypt and decrypt codes.
Matrices are used to calculate gross domestic product in economics, and thereby help in calculation for producing goods more efficiently.

Application of matrix in daily life

Matrices are used much more in daily life than people would have thought. In fact it is in front of us every day when going to work, at the university and even at home.

Graphic software such as Adobe Photoshop on your personal computer uses matrices to process linear transformations to render images. A square matrix can represent a linear transformation of a geometric object.

For example, in the Cartesian X-Y plane, the matrix \begin{matrix} 0 & -1 \\ 1 & 0 \end{matrix} reflects an object in the vertical Y axis. In a video game, this would render the upside-down mirror image of an assassin reflected in a pond of blood. If the video game has curved reflecting surfaces, such as a shiny metal shield, the matrix would be more complicated, to stretch or shrink the reflection.

In physics related applications, matrices are used in the study of electrical circuits, quantum mechanics and optics. Engineers use matrices to model physical systems and perform accurate calculations needed for complex mechanics to work. Electronics networks, airplane and spacecraft, and in chemical engineering all require perfectly calibrated computations which are obtained from matrix transformations. In hospitals, medical imaging, CAT scans and MRI's, use matrices to operate.

Whereas in programming which is taught at the university, matrices and inverse matrices are used for coding and encrypting messages. A message is made as a sequence of numbers in a binary format for communication and it follows code theory for solving.

In robotics and automation, matrices are the basic components for the robot movements. The inputs for controlling robots are obtained based on the calculations from matrices and these are very accurate movements.

Many IT companies also use matrices as data structures to track user information, perform search queries, and manage databases. In the world of information security, many systems are designed to work with matrices. Matrices are used in the compression of electronic information, for example in the storage of biometric data in the new Identity Card in Mauritius.

In geology, matrices are used for making seismic surveys. They are used for plotting graphs, statistics and also to do scientific studies and research in almost different fields. Matrices are also used in representing the real world data’s like the population of people, infant mortality rate, etc. They are best representation methods for plotting surveys. In economics very large matrices are used for optimization of problems, for example in making the best use of assets, whether labour or capital, in the manufacturing of a product and managing very large supply chains.
