  • If x is nonnumeric, BesselJ generates an error value.

  • If n is nonnumeric, BesselJ returns the generates an error value.

  • If n < 0, BesselJ generates an error value.

  • The n-th order Bessel function of the variable x is: Ff836810.awfbslj1_ZA06051116(en-us,office.14).gifwhere: Ff836810.awfbslj2_ZA06051117(en-us,office.14).gifis the Gamma function.
