关于图像的中心平移问题

anelkaymh

dirname='.\new\00002.txt';
channelnum = 4;

datafile = fopen(dirname);
data_tmp = fread(datafile,'integer*2');
fclose(datafile);

data = zeros(channelnum,length(data_tmp)/channelnum);
for i = 1:channelnum
    data(i,:) = (data_tmp(i:channelnum:end)).';
    data(i,:) = data(i,:)-mean(data(i,:));
end


data_pro = data(4,:);

data_len = 6400;

figure;plot(data_pro);
这段程序中怎么将图像的中心平移到原点，也就是左移3200个单位，最好有程序阿

图像和矩阵的平移有专门的指令fftshift
