Matriz householder
In der Mathematik beschreibt die Householdertransformation die Spiegelung eines Vektors an einer Hyperebene durch Null im euklidischen Raum. Im dreidimensionalen Raum ist sie somit eine Spiegelung an einer Ebene (durch den Ursprung). Die Darstellung dieser linearen Abbildung durch eine Matrix wird als Householder-Matrix bezeichnet. Verwendung findet sie vor allem in der numerischen Mathematik, wenn mittels orthogonaler Transformationen Matrizen so gezielt umge… WebHouseHolder matrix 作用之一就是其次坐标向量，或者模长为1的向量过参数向量优化的过程中会使用，HouseHolder matrix P 将某一向量 X 映射为 Y = PX = X e^1 ,将向量映射投影到了某以主轴上，应保证模长不变。. 如 …
