python：numpy数组的矩阵列表？

Question

我有一个包含numpy矩阵的列表。无论如何，我可以把整个东西变成一个漂亮干净的numpy数组？

自：

[matrix([[1]]), matrix([[ 1.99387871]]), matrix([[ 2.53564618]]), matrix([[ 4.39125807]]), matrix([[ 4.246309]]), matrix([[ 5.21571607]]), matrix([[ 6.17408811]]), matrix([[ 4.75146571]]), matrix([[ 6.19319742]]), matrix([[ 6.1277607]]), matrix([[ 7.43821216]])]

要：

[[1 1.99387871 2.53564618 4.39125807 4.246309 5.21571607 6.17408811 4.75146571 6.19319742 6.1277607 7.43821216]]

Answer 1

b = np.asarray(a, dtype=float)
#to get the same shape do.
b = b.reshape(-1, len(b)) 
#to just get one dimmension do. 
b = np.asarray(a, dtype=float).reshape(len(a))
