Matlab中出错了,>> k1=0:50;w=0.08*pi;s=cos(w*k1);N=50;k2=0:N-1;d=rand(1,N);x=s+d;subplot(3,1,1);stem(d);subplot(3,1,2);stem(x);subplot(3,1,3);stem(s)Error using ==> plusMatrix dimensions must agree.
Matlab中出错了,
>> k1=0:50;
w=0.08*pi;
s=cos(w*k1);
N=50;
k2=0:N-1;
d=rand(1,N);
x=s+d;

说的是你用加法的两个数长度不一致;
程序里s是51个,d只有1位,
你希望的应该是给每个数都加上一个随机数,还是改成下面的吧:
for i = 0:50
x(i+1) = s(i+1)+rand(1,N)
end
