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.
