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： (b%&DyOt
%Display the Zernike function Z(n=5,m=1) jPU:&1(_ n
clc CIAHsbn.A
clear oV"#1 lp*
a=5;%%%%%%%%%%Z的阶数下标 6 =A
b=1;%%%%%%%%%%Z的阶数的上标 0)n#$d>
x = -1:0.01:1; hbdq'2!Qr
[X,Y] = meshgrid(x,x); '*H&s
[theta,r] = cart2pol(X,Y); |2w,Np-
idx = r<=1; 'oSs5lW
z = nan(size(X)); w:%3]2c
z(idx) = zernfun(a,b,r(idx),theta(idx)); mTXeIng?
