线性代数（linear algebra） Linear algebra (Linear Algebra) is a branch of mathematics. Its research objects are vectors, vector spaces (or linear spaces), linear transformations and finite dimensional linear equations. Vector space is an important subject in modern mathematics. Therefore, linear algebra is widely used in abstract algebra and functional analysis. Linear algebra can be expressed concretely by analytic geometry. The theory of linear algebra has been generalized to operator theory. Since nonlinear models in scientific research can often be approximated as linear models, linear algebra has been widely applied to natural and social sciences. The development of linear algebra Because the work of Descartes and Fermat, linear algebra basically appeared in seventeenth Century. Until the late eighteenth Century, the field of linear algebra was confined to planes and spaces. The first half of nineteenth Century to complete the transition matrix to the n-dimensional vector space theory begins with Kailai in the second half of nineteenth Century, because if when work reached its culmination in.1888, Peano axiomatically defined finite or infinite dimensional vector space. Toeplitz will be the main theorem is generalized to arbitrary body linear algebra on the general vector space. The concept of linear mapping can in most cases get rid of matrix computation directed to the inherent reasoning, that is not dependent on the selection of the base. Do not exchange and exchange or not with the ring as the operator domain, this concept to die, this concept very significantly extended vector space theory and re organize the nineteenth Century Institute of the. The word algebra appeared relatively late in China, in the Qing Dynasty when the incoming China, it was translated into Alj Bala, until 1859, the Qing Dynasty famous mathematician, translator Li Shanlan translated it as algebra, still in use. The status of linear algebra Linear algebra is a subject that discusses matrix t
