将一个矩阵设置为另一个矩阵的元素

Question

is it possible to insert a matrix as an element of another matrix? for example, I have this matrix as c :

| A  | b |
| -------- | -------------- |
| c11    | c12            |
| c21   | c22            |

now assume that I want to set this matrix as c11:

| g  | h |
| -------- | -------------- |
| r11    | r12            |
| r21    | r22            |

is it possible in python?

Answer 1

c11 = np.array([[r11,r12],[r21,r22]])
c12 = np.array([[r11,r12],[r21,r22]])
c21 = np.array([[r11,r12],[r21,r22]])
c22 = np.array([[r11,r12],[r21,r22]]) 

c = np.array([[c11,c12],[c21,c22]])
