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： =|DkD-

%Display the Zernike function Z(n=5,m=1) _R>s5|_

a=5;%%%%%%%%%%Z的阶数下标 gK] T}
b=1;%%%%%%%%%%Z的阶数的上标 X.r!q1_c
x = -1:0.01:1; gwkZk-f\p
[X,Y] = meshgrid(x,x); #,Fx@3y\a
[theta,r] = cart2pol(X,Y); FQv02V+&<
idx = r<=1; hfP(N_""S
z = nan(size(X)); . pNq-T
z(idx) = zernfun(a,b,r(idx),theta(idx)); E!O(:/*
