Not necessarily, a rectangle is ok, and this is not necessarily a square. Square array is a kind of formation used by ancient troops in combat, which is to arrange troops in a square formation on an open field.

The ancient phalanx consists of the former army, the middle army and the rear army nested with each other. The square plane presents a "Hui" shape, which reflects a political and geographical structure in ancient concepts and comes from the world view of "the sky is round and the place is round".

A square matrix is a matrix with as many rows as columns, and a matrix is a group of complex numbers or real numbers arranged in a rectangular array. 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.

The Significance of Math Square Team

Mathematically speaking, a square queue means a square queue. N×n matrix is called n matrix, that is, a matrix with as many rows as columns. 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. 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.
