在 MATLAB Online 中打开

filename = 'onetwo.dat';
outfilename = 'onetwo_slim.dat';
%read the content of the existing file
S = fileread(filename);
%remove extra sequential line terminators 
SS = regexprep(S, '(\r?\n)(\r?\n)*', '$1');
%write a new file from the result
fid = fopen(outfilename, 'w');
fwrite(fid, SS);
fclose(fid);
