How to create identity matrix with numpy

Question

How do I create an identity matrix with numpy? Is there a simpler syntax than

numpy.matrix(numpy.identity(n))

Answer 1

Also np.eye can be used to create an identity array (In).

For example,

>>> np.eye(2, dtype=int)
array([[1, 0],
       [0, 1]])
>>> np.eye(3, k=1)
array([[ 0.,  1.,  0.],
       [ 0.,  0.,  1.],
       [ 0.,  0.,  0.]])
