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： -w B AFr
%Display the Zernike function Z(n=5,m=1) ^> fs
clc O;2 u1p'iP
clear c+=&5=i[3
a=5;%%%%%%%%%%Z的阶数下标 SCij5il%

x = -1:0.01:1; HdM;c*K
[X,Y] = meshgrid(x,x); Cmj) CJ-
[theta,r] = cart2pol(X,Y); . +>}},
idx = r<=1; jTnu! H2o
z = nan(size(X)); @zbXG_J
z(idx) = zernfun(a,b,r(idx),theta(idx)); GSp1,E2J
