matlab 相乘维数不一致

function [mseq]= m_sequence(fbconnection);
fbconnection=[0 1 0 0 1];
mseq = m_sequence(fbconnection);
mseq;
n = length(fbconnection);
N = 2^n-1;
register = [zeros(1,n - 1) 1];%定义移位寄存器的初始状态
mseq(1)= register(n);
for i = 2:N

newregister(1)= mod(sum(fbconnection.*register),2);

for j = 2:n,

newregister(j)= register(j-1);

end;

register = newregister;

mseq(i) = register(n);
end
dt=1;
t=(0:dt:31);
x=cos(t);
y=mseq;
plot(x.*y);
运行的时候最后一行报错，说是维数不一致，请哪位高手告诉我该怎么做啊

plot(x.*y);这个语法有问题吧;另外是你x和y中的元素个数不相等
