程序中data0为一个含有2500个数据的数组,
其中报错如下：
Index exceeds matrix dimensions.
Error in ==> middlefilter at 13
out(i)=mean(s(i+1:i+n1-2));
谁知道为什么吗,怎么修改

试着写了一个,LZ试试看行不行：
clear
clc
x = 1:2500;
y = randn(1,2500);
n=17; %中值滤波窗口
for i = 1:length(y)-n+1
yy = y(i:i+n-1);
out(i) = mean(yy(~((yy == min(yy))|(yy == max(yy)))));
end
subplot(2,1,1);
plot(x,y);
subplot(2,1,2);
outx = x(1:length(y)-n+1);
plot(outx,out);
