matlab就自带了好多个

1. bessel Bessel functions of various kinds.
   
2.     Bessel functions are solutions to Bessel's differential
   
3.     equation of order NU:
   
4.              2                    2    2
   
5.             x * y'' +  x * y' + (x - nu ) * y = 0
   
6. 
   
7.     There are several functions available to produce solutions to
   
8.     Bessel's equations.  These are:
   
9. 
   
10.         BESSELJ(NU,Z)    Bessel function of the first kind
    
11.         BESSELY(NU,Z)    Bessel function of the second kind
    
12.         BESSELI(NU,Z)    Modified Bessel function of the first kind
    
13.         BESSELK(NU,Z)    Modified Bessel function of the second kind
    
14.         BESSELH(NU,K,Z)  Hankel function
    
15.         AIRY(K,Z)        Airy function
    
16. 
    
17.     See the help for each function for more details.
