Examples

>>> import numpy as np
>>> import mindspore
>>> from mindspore import Tensor, ops
>>> a = Tensor(np.array([2.0, 4.0, 6.0, 8.0]).astype(np.float32))
>>> x = Tensor(np.array([2.0, 3.0, 4.0, 5.0]).astype(np.float32))
>>> igamma = ops.Igamma()
>>> output = igamma(a, x)
>>> print (output)
[0.593994  0.35276785  0.21486944  0.13337152]
>>> a = Tensor(2.1, mindspore.float32)
>>> x = Tensor(2.1, mindspore.float32)
>>> igamma = ops.Igamma()
>>> output = igamma(a, x)
>>> print (output)
