◆ besi0()

def besi0	(	x	,
		kode	= `1`
	)

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: float
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] kode (Optional)
A parameter to indicate the scaling option.
= 1: No scaling.
= 2: Returns exponentially scaled values. (For other values, kode = 1 is assumed.)
