The book is self-contained, with appendices included on elementary matrix and laplace transforms . 本书自成体系,并有初等阵论及拉普拉斯变换的附录。
The brief proof is given for " row elementary operations keep the linear relationship of column vectors of matrix " , by using multiplication of partitioned matrix and the relation between elementary matrix and elementary operation 摘要利用初等矩阵与初等变换的对应关系及分块矩阵的乘法,给出“矩阵的行初等变换不改变其列向量组的线性关系”的一个简易证明。
百科解释
In mathematics, an elementary matrix is a matrix which differs from the identity matrix by one single elementary row operation. The elementary matrices generate the general linear group of invertible matrices.
