BESSELJ function

Returns the Bessel function.

Syntax

BESSELJ(x,n)

X     is the value at which to evaluate the function.

N     is the order of the Bessel function. If n is not an integer, it is truncated.

Remarks

  • 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:
