  1. Mar 31, 1999 · (原作者 wlsk) 黑客帝国的剧情比较难懂,而且电影融入了大量哲学元素,如存在主义、结构主义、宿命论、虚无主义等等。解析剧情的帖子网上有不少,这里我想讨论的不是剧情,而是在假设读者熟悉电影的情况下说说为什么留在Matrix里才是一个合理的选择。

  2. 1 个回答. 要想弄清楚为什么Matrix被译为“矩阵”,首先来了解一下相关的数学发展史。. 1850年,英国数学家西尔维斯特在其文章中 [1] 首次将英文中"Matrix" 一词用于表示“矩阵”之意,为数学创作了一个新的词汇。. 他在文中写道:. For this purpose we must commence, not ...

  3. The projection matrix \bm {P} is m by m, but its rank is one. We are projecting onto a one-dimensional subspace, the line through \bm {a} . That line is the column space of \bm {P} . Projecting a second time doesn't change anything, so \bm {P^2=P} . When \bm {P} projects onto one subspace, \bm {I-P} projects onto the perpendicular subspace.

  4. The matrix is a computer-generated dreamworld, built to keep us under control, in order to change human being into this. This intriguing metaphor captured me “What actually is the Matrix?” It can be the society or the history of mankind that we push forward.

  5. The Design Structure Matrix (DSM – also known as the dependency structure matrix, dependency source matrix, and dependency structure method) is a general method for representing and analyzing system models in a variety of application areas. A DSM is a square matrix (i.e., it has an equal number of rows and columns) that shows relationships ...

  7. Dec 16, 2021 · A matrix with trace 0 is similar to a hollow matrix (namely, a matrix where all diagonal entries are 0). Proposition 2. Hollow matrices are commutators (matrices in the form of AB-BA). Proposition 3. The dimension of the space of n by n hollow matrices is n^2-n. Proposition 4. \operatorname {trace} (AB-BA)=0.

  8. Dec 22, 2021 · 黑客帝国:矩阵重启的剧情简介 · · · · · ·. 尼奥(基努·里维斯 Keanu Reeves 饰)和崔妮蒂(凯瑞-安·莫斯 Carrie-Anne Moss 饰)重回矩阵:在这里,一个是矩阵创造出来,周而复始的日常世界,另一个则是隐藏其后,真实的人类世界。. 为了弄清楚自己所处的 ...

  9. Aug 11, 2009 · Matrix做为生产工具,唯一的衡量标淮是生产效率的提高。The Architect(设计师)设 计的第一代Matrix是按人类理想设计的一个完美的世界,原以为人人会安居乐业,但却 不想由于人类的劣根性,导致人类(或称“粮食“)大量坏死,于是,The Architect只好

  10. 以下是关于matrix permanent的两个有趣事实: 在计算复杂性中, Leslie Valiant证明了准确计算determinant是#P-hard的. 不过对于非负矩阵仍然存在多项式时间的近似算法. van der Waerden猜想, 对于任意doubly stochastic matrix P , 其permanent的最小值是 \frac {n!} {n^n} , 并且在 P_ {ij}=\frac {1 ...
