The part of speech of matrix is: noun. The structure is: rectangular (left and right structure) array (left and right structure). The phonetic notation is: ㄐㄨˇㄓㄣ _. The pinyin is: j ǔ zhè n.
What is the specific explanation of matrix? We will introduce you through the following aspects:
I. Text Description Click here to view the details of the plan.
One of a set of rectangular arrangements of mathematical elements (such as the coefficients of simultaneous linear equations) of matrix j ǔ zhè n. (1) follows special algebraic laws.
Second, the national language dictionary
These elements are arranged in a rectangular structure with straight lines and horizontal lines. For example, in mathematics, the coefficients of multiple equations are often arranged in a matrix, and the unknowns are solved through the operation of the matrix. Matrix in computer circuit refers to a group of circuits with special arrangement, which is used to broaden signal processing or cooperate with bus transmission.
Third, the network interpretation
Matrix (mathematical terminology) In mathematics, a matrix is a group of complex numbers or real numbers arranged in a rectangular array, which originated from a square matrix composed of coefficients and constants of an equation. This concept was first put forward by British mathematician Kelly in19th century. Matrix is a common tool in applied mathematics such as advanced algebra and statistical analysis. In physics, matrices have applications in circuit science, mechanics, optics and quantum physics. In computer science, three-dimensional animation also needs matrix. Matrix operation is an important problem in the field of numerical analysis. Decomposition of a matrix into a combination of simple matrices can simplify the operation of the matrix in theory and practical application. For some widely used and special matrices, such as sparse matrix and quasi-diagonal matrix, there are concrete fast operation algorithms. For the development and application of matrix related theory, please refer to matrix theory. Infinite-dimensional matrices will also appear in astrophysics, quantum mechanics and other fields, which is the generalization of matrices. The main branch of numerical analysis is devoted to the development of effective algorithms for matrix calculation, which has been a topic for centuries and an expanding research field. The matrix decomposition method simplifies the theoretical and practical calculation. The customized algorithm for specific matrix structures (such as sparse matrix and near-angle matrix) speeds up the operation speed in finite element method and other calculations. Infinite matrix appears in planetary theory and atomic theory. A simple example of infinite matrix is the matrix representing the derivative operator of Taylor series of functions.
