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).......
