Suppose we have a matrix
A = 1 2 3 4
15 20 7 10
0 5 18 12
And an adjacency matrix
B = 1 0 1
0 0 1
1 1 1
如果B [i,j] == 1,我们如何获得包含每一行A行平均值的新矩阵
Expected output matrix
C = 0.5 3.5 10.5 8
7.5 12.5 12.5 11
5.33 9 9.33 8.66
要查找每个i的邻域,我实现了以下代码:
for i in range(A.shape[0]):
for j in range(A.shape[0]):
if (B[i,j] == 1):
print(j)```
