均值滤波程序.m

本人利用MATLAB处理了并总结了工程上经常用到的“信号处理”的源代码

%均值滤波
n=20;
x=[0.194,0.188,0.182,0.191,0.203,0.186,0.196,0.181,0.200,0.192 0.183,0.185,0.191,0.197,0.202,0.187,0.189,0.195,0.189,0.193];
y=zeros(n,1);			%改变存放平均值数组大小
y(1)=x(1);			    %第一个平均值
for i=2:n   			%计算第2-20个平均值
    y(i)=y(i-1)+(x(i)-y(i-1))/i;
end
plot(y,'.-r')
