我需要将数百个文本文件作为单个矩阵导入，但每个文本文件都有6行垃圾标题，我想忽略/删除。文本文件以制表符分隔。我只需要从第7行开始将每个文件作为唯一矩阵导入。每个文件中有149列，长度范围为400-1500行。这该怎么做？另外，我如何将每个文件的第5列绘制到同一个图上？
这就是我目前正在尝试的工作：
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
这就是文本文件的样子：

我认为dlmread会更好。同样适用于您的情况，因为您声明文件的长度差异很大，因此使用单元格数组将是更好的选择。
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
