Returns the value of the modified Bessel function.
-
nu
-
specifies a numeric constant, variable,
or expression.
Range: |
nu 0 |
-
x
-
specifies a numeric constant, variable,
or expression.
Range: |
x 0 |
-
kode
-
is a numeric constant, variable, or expression
that specifies a nonnegative integer.
The IBESSEL function returns the value
of the modified Bessel function of order nu evaluated at x (Abramowitz, Stegun 1964; Amos, Daniel, Weston 1977). When kode equals 0, the Bessel function is
returned. Otherwise, the value
of the following function is returned:
