二楼得到的是一个向量，而非方矩阵。

需做一点改动。

clear;
clc;
a = 1;
N = 20;
n = -N/2:N/2-1;
k = 2*pi*n/N/a;

w = abs(sin(k*a/2));
miu = 2*pi/N/a;

omiga = miu*meshgrid(w, w).*dial(1, ...

N = 20;a=1;
n = -N/2:N/2-1;
k = 2*pi*n./N/a;

w = abs(sin(k.*a./2));
miu = 2*pi/N/a;
omica = w.*miu*diag(ones(1,length(n)));

谢谢，但是这样得到的omica是向量，根据定义应该是一个矩阵对吧...
