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： ~V-XEQA
%Display the Zernike function Z(n=5,m=1) <m m [S
clc >bxS3FCX
clear yLGRi^d#
a=5;%%%%%%%%%%Z的阶数下标 q@&6#B
b=1;%%%%%%%%%%Z的阶数的上标 H. c7Nle
x = -1:0.01:1; sRW<me;
[X,Y] = meshgrid(x,x); rZF*q2?
[theta,r] = cart2pol(X,Y); OPi 0~s
idx = r<=1; `gJ( 0#ac
z = nan(size(X)); Vj-h;rB0z
z(idx) = zernfun(a,b,r(idx),theta(idx)); 7"##]m.
