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： `S
{&gl
%Display the Zernike function Z(n=5,m=1) x e`^)2z
clc Z3`EXs
clear ,EB}IG ]
a=5;%%%%%%%%%%Z的阶数下标 -#|D>
b=1;%%%%%%%%%%Z的阶数的上标 I%[e6qX@
x = -1:0.01:1; ux; ?WPyr
[X,Y] = meshgrid(x,x); P$)g=/td1
[theta,r] = cart2pol(X,Y); ^ Bx[%
idx = r<=1; j J ,_-ui
z = nan(size(X)); f O*jCl
z(idx) = zernfun(a,b,r(idx),theta(idx)); S#/%#k103
