# Applications of Matrices in Mathematics and Real Life

In mathematics, matrices play an essential role for students to score good marks. Matrix is one of the crucial concepts in linear algebra. The applications of matrices are not limited to any particular field since they have many applications in mathematics and other areas, including real-life situations. Matrices are an indispensable tool in expressing and handling problems that arise from real-life issues. Matrices are applied to compare electrical circuits, quantum mechanics, and optics to calculate battery power outputs and resistor transformation of electrical energy to different useful energy.

Matrices play a significant role in projecting three-dimensional images into a two-dimensional screen, creating realistic seeming motion. Matrices are used to calculate the GDP, i.e. gross domestic products in economics, which eventually helps calculate the production of the goods efficiently. However, we often use an inverse matrix in three-dimensional, i.e. 3D modelling and transformation. Besides, matrices are the root elements for robot movements. Here, the actions of robots are programmed with the estimation of rows and columns of matrices. To control robots, the inputs can be provided based on the estimates from matrices. Matrices are also used in various situations by scientists to record the data of their experiments.

There are several mathematical applications of matrices. Suppose a square matrix can represent a linear transformation of a geometrical object. Also, matrices represent linear maps and allow explicit computations in linear algebra. In geometry, matrices are widely used for specifying and describing geometric transformations such as rotations and coordinate changes. In numerical analysis, we can solve many mathematical problems by reducing them in the form of a matrix based computation, which often involves computing with matrices of enormous dimension. Matrices are used in many branches of mathematics and scientific fields, either directly or using other applications such as geometry and numerical analysis.

The field of statistics probability may also use matrix representations. Matrix mathematics simplifies linear algebra, at least in providing a more compact way to deal with a system of equations in linear algebra. Hence, the study of matrices is a vast part of linear algebra, and we can express most properties and operations of abstract linear algebra in terms of matrices. Suppose, matrix multiplication describes the composition of linear maps. However, not every matrix is associated with linear algebra. Apart from these, in group theory, a matrix group consists of invertible matrices over a particular field, with a matrix multiplication operation.

Matrix mathematics has several applications apart from the ones mentioned earlier. Matrices provide very compact methods of putting together a lot of information. Matrices are used much more in daily life than people would have thought. Mathematicians, engineers, and scientists express groups of equations as matrices and these can be solved in a systematic way. Also, we know that matrices are such concepts that can be understood easily and quickly. Moreover, the applications of matrices are also not limited to only a few fields, and we can observe them in many areas of mathematics and our daily existence.
