zernike多项式的matlab编程表示图例
采用matlab编程，其主函数如下，可以模拟各阶的zernike多项式： #<l ;YT8
%Display the Zernike function Z(n=5,m=1) z+wBZn{0I
clc a:@Eg;aN*O
clear H# Vs3*VK
a=5;%%%%%%%%%%Z的阶数下标 HgG"9WBe%
b=1;%%%%%%%%%%Z的阶数的上标 <4Ujk8Zj
x = -1:0.01:1; < v0 d 8
[X,Y] = meshgrid(x,x); @0t,vye
[theta,r] = cart2pol(X,Y); 6IeHZ)jGj
idx = r<=1; Dwwh;B
z = nan(size(X)); [j:%O|h
z(idx) = zernfun(a,b,r(idx),theta(idx)); qzV:N8+,`
