numpy.i0()函数| Python

numpy.i0()函数是第一类修正的贝塞尔函数，0 阶。它通常用 I ₀表示。

Syntax : numpy.i0(x)
Parameters :
x : [array_like, dtype float or complex] Argument of the Bessel function.

Return : [ndarray, shape = x.shape, dtype = x.dtype] The modified Bessel function evaluated at each of the elements of x.

代码#1：

# Python program explaining
# numpy.i0() function
  
# importing numpy as geek 
import numpy as geek
  
gfg = geek.i0(0.)
  
print (gfg)

输出 ：

1.0

代码#2：

# Python program explaining
# numpy.i0() function
  
# importing numpy as geek 
import numpy as geek
  
gfg = geek.i0([1., 2. + 3j])
  
print (gfg)

输出 ：

[ 1.26606588+0.j,  -1.24923489+0.9479838j]
