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： JxU5 fe
%Display the Zernike function Z(n=5,m=1) iy.\=Cs$N
clc X:{!n({r=

x = -1:0.01:1; OY({.uV dX
[X,Y] = meshgrid(x,x); ?a]mDx>xh
[theta,r] = cart2pol(X,Y); #/37V2E
idx = r<=1; H\[W/"
z = nan(size(X)); qH_Dc=~la
z(idx) = zernfun(a,b,r(idx),theta(idx)); \i &< s;
