Hi Matlab Users,

I have a folder containing more than 10,000 text files (each file dimension is 12997rows x 1column). I wanted to remove the first row of all the files and insert a three row header (Text, 1/1/1979, 12/31/2014) in all the files. Can anyone help me in this regard.

Thanks in Advance.

Regards, Gokul

在 MATLAB Online 中打开

EDIT

f='C:\Users\mal\Documents\MATLAB'  % your folder containing your text files
fi=dir(fullfile(f,'*.txt'))
file={fi.name}
text={'Text'; '1/1/1979',; '12/31/2014}'}
for ii=1:numel(file)
  fic=fullfile(f,file{ii})
  fid=fopen(fic)
  s=textscan(fid,'%s','headerlines',1,'delimiter','\n')
  fclose(fid)
  out=[text;s{:}]
  fid=fopen(fic,'w')
  for k=1:numel(out)
      fprintf(fid,'%s\r\n',out{k})
  end
  fclose(fid)
