Kronecker积逼近 (Kronecker product approximation) 问题又被称为nearest Kronecker product问题,一般简称为NKP问题,是矩阵计算和张量计算中非常重要的逼近问题。今天,我们将介绍Kronecker积逼近问题的基本表达式以及经典求解方法。 1 初识Kronecker积逼近问题 Kronecker积是张量计算中十分常见的一种运算规则,通常用符号 ⊗ ...
Kronecker积(Kronecker Product) Kronecker积是两个矩阵的张量积,记作A⊗B。具体来说,如果A是m×n矩阵,B是p×q矩阵,则A⊗B是一个mp×nq的矩阵,其元素由以下公式给出: (A⊗B)i,j=Ai′,j′Bi″,j″ 其中i=(i′−1)p+i″且j=(j′−1)q+j″,1≤i′≤m,1≤j′≤n,1≤i″≤p,1...
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...
