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： \B#tB?rA
%Display the Zernike function Z(n=5,m=1) UyRy>:n
clc CzBYH
clear s[8. l35|
a=5;%%%%%%%%%%Z的阶数下标 w;,34qbf
b=1;%%%%%%%%%%Z的阶数的上标 H_?rbz} o
x = -1:0.01:1; b<tV>d"Fv
[X,Y] = meshgrid(x,x); j:%,l cF
[theta,r] = cart2pol(X,Y); %RD\Sb4YV
idx = r<=1; AMyg>n!
z = nan(size(X)); *q6XK_
z(idx) = zernfun(a,b,r(idx),theta(idx)); :Q`Of}#
