Deepcopy of a Matrix SageMath
I am creating a deepcopy of a Matrix in SageMath.
import copy
A = Matrix([[1,2],[3,4]]).augment(Matrix.identity(2), subdivide=True)
B = copy.deepcopy(A)
print A
print B
Gives me:
[1 2|1 0]
[3 4|0 1]
[1 2 1 0]
[3 4 0 1]
What is the correct way to deepcopy a matrix with the subdivision? Do I have to use:
B.subdivide(*A.subdivisions())

I did not know about ask.sagemath before. This is a repost of stackoverflow .com /questions/41322359/deepcopy-of-a-matrix-sagemath (my karma is not enough to post links).
