MATLABText Analytics Toolbox

How can I erase the same row (row #3) in multiple TXT files using MATLAB code?

Best Answer

Please take a look at the example code below which deletes the 3rd row of TXT files present in the current directory. The code reads in the TXT files in the current directory, deletes the 3rd row and saves the modified files to a new folder
 
files = dir('*.txt') ; %read all txt files in current directory
N = length(files) ;
mkdir newFiles % create new folder
for i = 1:N
  filename = files(i).name ;
  A=importdata(filename);
  A(3)=[];  %delete 3rd row
  fid = fopen(['newFiles/' filename],'wt');
  fprintf(fid,'%s\n', A{:});
  fclose(fid);
end
