numpy.i0() function | Python

numpy.i0() function is the modified Bessel function of the first kind, order 0. it’s usually denoted by I₀.

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.

Code #1 :

# Python program explaining
# numpy.i0() function

# importing numpy as geek
import numpy as geek

gfg = geek.i0(0.)

print (gfg)

Output :

1.0

Code #2 :

# Python program explaining
# numpy.i0() function

# importing numpy as geek
import numpy as geek

gfg = geek.i0([1., 2. + 3j])

print (gfg)

Output :

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