Excel - BESSELJ Function



Description

The BESSELJ function returns the Bessel function Jn(x).

Syntax

BESSELJ(X, N)

Arguments

Argument Description Required/ Optional
X The value at which to evaluate the function. Required
N The order of the Bessel function. If n is not an integer, it is truncated. Required

Notes

  • If x is nonnumeric, BESSELJ returns the #VALUE! Error value.

  • If n is nonnumeric, BESSELJ returns the #VALUE! Error value.

  • If n < 0, BESSELJ returns the #NUM! Error value.

  • The n-th order Bessel function of the variable x is −

    Jn(x)=k=0(1)kK!Γ(n+K+1)(x2)n+2k

    Where −

    Γ(n+K+1)=0enxn+kdx

Applicability
