how to write text files in a specific format?

Hello, Below is my code that would write data into a text file.

    fileID = fopen('G:\FLOW_OUT_32.txt','w');
  formatSpec = '%d %2.5f \n';
  [nrows,ncols] = size(output32);
  for row = 1:nrows
      fprintf(fileID,formatSpec,output32{row,:});
  end
  fclose(fileID);

I would like the data to be written in the format shown below. Any help would be appreciated. Thanks

You shouldn't need a loop.

 fileID = fopen('G:\FLOW_OUT_32.txt','w');
 fprintf(fileID,'%d %12.6e\n',output32.'); %assuming out32 is a nx2 matrix
 fclose(fileID);
