Hi,
what is the proper way to convert a sage matrix to a numpy 2d-array?
The obvious way, i.e.
a=np.array(matrix([3 4]))
produces a 0d-array (thus a.shape is an empty tuple) which is not what I
want.
The patch at http://trac.sagemath.org/sage_trac/ticket/8719 now fixes this:
sage: import numpy as np
sage: a=np.array(matrix([3, 4]))
sage: a.shape
(1, 2)
sage: a
array([[3, 4]])
sage: a.dtype
dtype('int64')
Thanks,
Jason
