biometrics number is a branch of math one that studies vector, vector spatial (or biometrics spatial), biometrics transformation and finite-dimensional biometrics Equation group. vector spatial is an important subject in modern math. biometrics substitution number is widely used in abstract substitution number and functional analysis. Through analytic geometry, the biometrics substitution number can be concretely represented. biometrics substitution number theory has been generalized to operator theory. Since scientists studying non-Biometrics models can often be approximated as biometrics models, The biometrics generation number is widely used by Nature scientists, engineering, Calculator scientists and social scientists.

In math, matrices refers to a table of two-dimensional numbers arranged horizontally and horizontally, originally derived from the Equation group system number and constant number. This concept was first proposed by the 19th century English math writer Kelly.

matrices are common tools in advanced math and are also found in applied math disciplines such as statistical analysis. In physics, matrices have applications in circuits, mechanics, optics, and quantum physics; Calculator scientists also use matrices for 3D animation. matrices calculate is an important problem in the field of number analysis. Decomposing matrices into simple combinations of matrices simplifies matrices calculate both in theory and in practical application. For some formality and special matrices, such as sparse matrices and quasi-diagonal matrices, there are some special fast calculate algorithms. For theoretical development and application of matrices, please refer to matrices Theory. In astrophysics, quantum mechanics and other fields, infinite dimensional matrices will also appear, which is a generalization of matrices one kind of.
