如何在导入多个文本文件时跳过标题行？

Question

我有数百个文本文件需要导入为单个矩阵，但每个文本文件都有6行垃圾邮件头，我想忽略/删除。文本文件是制表符分隔的。我只需要将每个文件从第7行开始作为唯一矩阵导入。每个文件有149列，长度范围为400-1500行。这个怎么做？另外，我会如何将每个文件的第5列绘制到同一个图上？

---

这就是我正在努力使工作：

txtfiles = dir('*.txt'); 
numfiles = length(txtfiles); 
for k = 1:numfiles 
    %textscan(txtfiles(k).name) 
    curname = txtfiles(k).name; 
    FID=fopen(curname); 
    datacell = textscan(FID, 'f%f%f%f', ... 
    'HeaderLines', 6, 'CollectOutput', 1); 
    fclose(FID); 
    A = datacell{1}; 
end 

这是文本文件的样子：

Answer 1

我觉得dlmread会更好。同样对于你的情况，如你所说这些文件的长度差异很多，所以使用单元阵列将是一个更好的选择。

hold on; 
datacell = cell(numfiles,1); %Pre-allocation 
for k=1:numfiles 
    datacell{k} = dlmread(txtfiles(k), '', 6, 0); %skipping 6 rows and zero columns 
    plot(datacell{k}(:,5));  %to plot 5th column of each file 
end
