◆ besi0()

function besi0	(	x::Real	,
		scaling::Bool	= `false`
	)

Modified Bessel functions of the first kind of order zero I0(x)

Purpose: besi0 computes the modified Bessel function of the first kind of order zero I0(x).

Returns: Float64
Modified Bessel function of the first kind of order zero I0(x). (if kode = 1)
Exponentially scaled modified Bessel function of the first kind of order zero exp(-|x|)*I0(x). (if kode = 2)

Parameters

[in] x Argument x.

Error handling

Range error (ERANGE) may occur.

Parameters

[in] scaling (Optional)
A parameter to indicate the scaling option. (default = false)
= false: No scaling.
= true: Returns exponentially scaled values.
