axis([0,20,-1,1]);title('0阶、一阶、二阶第一类贝塞尔函数曲线图');xlabel('Variable X');ylabel('Variable Y');第二类贝塞尔函数(诺依曼函数)在MatLab中用用bessely(NU,Z)来表示:clear ,clc;format long x=(0:0.01:20)';y_0=bessely(0,x);y_1=bessely(1,x);y_2=bessely...
如题,我想用贝塞尔函数表示艾里函数如AI(z),AI'(z),BI(z),BI'(z)?其中AI(z),AI'(z),表示第一种艾里函数及关于z的导数,BI(z),BI'(z)表示第二种艾里函数及关于z的导数... 如题,我想用贝塞尔函数表示艾里函数如AI(z),AI'(z),BI(z),BI'(z)?其中AI(z),AI'(z),表示第一种艾里函数及...
可以用离散积分思路写程序,如下:clc;clear;close all;k=1;a=1;theta=linspace(0,pi,1001);theta(...
不用混编,直接用_jn。double _jn( int n, double x );这是Help:_j0, _j1, _jn These routines return Bessel functions of the first kind: orders 0, 1, and n, respectively.Example include <math.h> include <stdio.h> int main( void ){ double x = 2.387;int n = 3, ...
在MatLab中用besselj(NU,Z)来表示:用MatLab的仿真代码是:clear ,clc;format long x=(0:0.01:20)';y_0=besselj(0,x);y_1=besselj(1,x);y_2=besselj(2,x);plot(x,y_0,x,y_1,x,y_2);grid on;axis([0,20,-1,1]);title('0阶、一阶、二阶第一类贝塞尔函数曲线图');xlabe...
