利用householder 变换, 将a 化为对称三对角矩阵,即计算正交矩阵q 使得t = qaq⊺ 为对称三对角矩阵; W hat’s more, the paper has introduced parametric characteristic modeling technology and ana lyzed the data structure to. Model of the characteristic and parameter thoughts is p vided.
Unmasking “Masking” What It Is, and Why We Do It
, in the study on ball bearing fault diagnosis based on wavelet transform , the parameter selection of wavelet transform and computation of fault features cannot be carried out. 优点:可以计算所有特征值和特征向量缺点:收敛慢,运算太大,约o(n4) 实用的qr 迭代算法 先采用householder 变换,通过相似变换,将矩阵a 转化为上hessenberg 矩阵h ,运算量o(n3) 对h 进行.
