MATLAB中的各类贝塞尔函数

第一类贝塞尔函数：Jn（x） besselj(nu,Z) computes the Bessel function of the first kind, , for each element of the array Z. The order nu need not be an integer, but must be real. The argument Z can be complex. The result is real where Z is positive.
第二类贝塞尔函数：Yn（x） bessely(nu,Z) computes Bessel functions of the second kind, , for each element of the array Z. The order nu need not be an integer, but must be real. The argument Z can be complex. The result is real where Z is positive.
第三类贝塞尔函数：Hn（x） Bessel function of the third kind (Hankel function) besselh(nu,K,Z)
球贝塞尔函数：
function F = sphericalbessel?(n,x)
if x==0,
if n==0,
F = 1;
else
F = 0;
end
else
F=sqrt(pi/(2*x))*bessel?(n+0.5,x);
