Linear algebra is mainly a subject which studies the linear structure of finite dimensional linear space and its linear transformation while linear concept is in itself from the old euclid g eometry . the concept of " linear space " is a kind of algebraic abstract . in many fields of modern engineering project and technology , because of the influence of computer and graph showing , the algebraic disposal of geometric questions , the visual disposal of algebraic questions , algebra and geometry are tightly combined 線性代數(shù)主要是研究有限維線性空間及其線性變換這一代數(shù)結(jié)構(gòu)的學(xué)科,而線性概念究其根源則是來自古老的euclid幾何,線性空間概念是幾何空間的一種代數(shù)抽象,在現(xiàn)代工程技術(shù)的許多領(lǐng)域里,由于計(jì)算機(jī)及圖形顯示的強(qiáng)大威力,幾何問題的代數(shù)化處理,代數(shù)問題的可視化處理,把代數(shù)與幾何更加緊密地結(jié)合在一起。
