Chapter 4 矩阵乘法作为组合变换的形式以理解 It is my experience that proofs involving matrices can be shortened by 50% if one throws the matrices out read right to left 矩阵相乘的推导9. Complex Vectors and Matrices
9.1 Real versus Complex R= line of all real numbers (\(-\infty < x < \infty\)) \(\longleftrightarrow\) C=plane of all complex numbers \(z=x+iy\) |x| = absolute value of x \(\longleftrightarrow\) \(|z| = \sqrt{x^2+y^2} = r\)Appendix D: Graphics matrix operations
Great Microprocessors of the Past and Present (V 13.4.0) (cpushack.com) 3-D points are generally stored in four element vectors, defined as:[X, Y, Z, W]...where X, Y, and Z are the point 3-D coordinates, and W is the 'weight', and is used to nor半正交矩阵(定义)

Let \(M\) be regular (i.e. invertible, as defined in Hackbusch's book [Hie]) and \(M = \left( \begin{array}{cc} M_{11} & M_{12}\\ M_{21} & M_{22} \end{array} \right)\). To calculate the inverse of \(M\), perform the standard manuaSchur complement for inverting block matrices
