As far I have been able to verify, everything is correct until the definition of L. According to MATLABkron(Iy, Dx)(which is supposed to be the kronecker product) should produce a 35X35 matrix, but Python thinks it should be a 7X7 matrix. In simpler calculations, both give the correct...
在这里,我们也可以使用Python中的numpy定义一个permute函数: import numpy as np def permute(mat, A_dim1, A_dim2, B_dim1, B_dim2): ans = np.zeros((A_dim1 * A_dim2, B_dim1 * B_dim2)) for j in range(A_dim2): for i in range(A_dim1): ans[A_dim1 * j + i, :] = ...
result = np.kron(x, y): This line computes the Kronecker product of the two arrays x and y. The result is a 9x9 array formed by multiplying each element of x with the entire y array. print(result): This line prints the resulting Kronecker product, which is a 9x9 array. Python-Num...
克罗内克内积 Kronecker product ⊗ \otimes ⊗ 1.1 概述 克罗内克内积是一种特殊的张量积。任何两个形状的矩阵都可以进行克罗内克内积操作。 1.2 定义 Definition A ⊗ B A \otimes B A⊗B的定义:A是mxn矩阵,B是pxq矩阵。 A ⊗ B A \otimes B A&o... ...

Notice the assumption of independence is used in the second to last equality. But we can see here that the variance of the Kronecker product is the Kronecker product of the variances. Example 2: Your example in the (now-deleted) comments was an example where the two vectors were not indepe...
