function modzerobessel(const T1 &) other_math¶

template <numeric T1>
KFR_FUNCTION T1 modzerobessel(const T1& x)

Computes the modified zeroth-order Bessel function of the first kind. This function calculates I₀(x), the modified Bessel function of the first kind with order zero, for the given input value.

Template parameters

T1	The numeric type of the input parameter.

Parameters

x	The input value for which to compute the modified Bessel function

Returns

The computed value of I₀(x)
