WebExpert Answer. In problem 2 below, if the word "orthogonal" applied to Ψp(x,t) and Ψq(x,t) isn't clear, it means the following: when they are orthogonal you get exactly zero when their product Ψp∗(x,t)Ψq(x,t) is integrated over the entire box domain 0 ≤ x ≤ L. Complex conjugation (by adding the superscript ∗ ) MUST be applied to ... Web正交普鲁克问题 (Orthogonal Procrustes Problem) 是最接近的线性映射从一组向量 \\mathbf{A} 到另一组向量 \\mathbf{B} ，这里的两个矩阵代表向量集合。而线性映射通过 … The orthogonal Procrustes problem is a matrix approximation problem in linear algebra. In its classical form, one is given two matrices $${\displaystyle A}$$ and $${\displaystyle B}$$ and asked to find an orthogonal matrix $${\displaystyle \Omega }$$ which most closely maps See more This problem was originally solved by Peter Schönemann in a 1964 thesis, and shortly after appeared in the journal Psychometrika. This problem is equivalent to finding the nearest orthogonal … See more There are a number of related problems to the classical orthogonal Procrustes problem. One might generalize it by seeking the closest matrix in which the columns are See more • Procrustes analysis • Procrustes transformation • Wahba's problem See more hill gear
