BESSELI

Description

Returns the modified Bessel function, which is equivalent to the Bessel function evaluated for purely imaginary arguments. 

Sample Usage  



Syntax
 
  
   
  
 


BESSELI(X, N)


The BESSELI function syntax has the following arguments:


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



Notes
 
  
   
  
 


    
 
  • 
  
    If x is nonnumeric, BESSELI returns the #VALUE! error value.

    If n is nonnumeric, BESSELI returns the #VALUE! error value.
    
 
    • 
 
  • 
  
    If n < 0, BESSELI returns the #NUM! error value.
