Special Solutions: Notice what is special about s 1 and S2. They have ones and zeros in the last two components. Those components are "free" and we choose them specially. Then the first components -2 and -3 are determined by the equation Ax = 0.

概述 个人认为线性代数从三个角度,或者说三个工具来阐述了线性关系,分别是: 向量 矩阵 空间 这三个工具有各自的一套方法,而彼此之间又存在这密切的联系,通过这些抽象出来的工具可以用来干一些实际的活,最为直接的就是解方程组,进一步衍生出来最小二乘法等等. 这一部分主要讲了三个工具的各自的一些基本方法,以及用其解方程组的一套理论.另外,由于是总结,就不按照课程的顺序,而且各点之间都有穿插. 向量(Vector) 对于向量而言,大部分与中学一致,基本的就不说了,关注重点. 线性相关性 线性相关性用于描

转眼间我的学士学位修读生涯已经快要到期了,重读线性代数,一是为了重新理解Algebra的的重要概念以祭奠大一刷过的计算题,二是为了将来的学术工作先打下一点点(薄弱的)基础.数学毫无疑问是指导着的科研方向与科学发展,即使是同一本数学书,每次翻阅也能读出不同的内涵.享受不同的乐趣. P1-149 Strang在书的序言便给出了linear algebra的研究对象,一切的来源便在于Ax=b这个方程组.虽然从向量矩阵.线性方程组到向量空间.线性变换,费了好大劲才将任意一个线性变化凝练到一个矩阵上,但对
