MATLAB: Creation of a text file with a series of record set

MATLABrecord setseries of text datawriting in txt file

I want to give Number of record as N= 100 so that , in a txt file the follwing tempates is written 100 times by automatcially

changing the corresponding serial numbers for the values of each item.

The sample one record is as below:

One Sample

********************************************************
Patient ID      : H00001
Patient Name    : Name00001
Hospital Name   : Hos001
Reffered By     : Dr. Doctor001
Diease Symptom  : Diease001
Remark          : He is Suffereing from Diease 001

Try

cssm1()
dbtype test.txt 1:14

where

function cssm1()
    fid = fopen( 'test.txt', 'w' );
    assert( fid >= 3 )
    
    for jj = 1 : 100
        fprintf( fid, '********************************************************\n');
        fprintf( fid, 'Patient ID      : H00%03d\n', jj );
        fprintf( fid, 'Patient Name    : Name00%03d\n', jj );
        fprintf( fid, 'Hospital Name   : Hos%03d\n', jj );
        fprintf( fid, 'Reffered By     : Dr. Doctor%03d\n', jj );
        fprintf( fid, 'Diease Symptom  : Diease%03d\n', jj );
        fprintf( fid, 'Remark          : He is Suffereing from Diease %03d\n', jj );
    end
    fclose( fid );
end

MATLAB: How to add a new line in the middle of a text file

There is no "smart" way. One has to read the existing file and write the new. If the file isn't too large this could be a starting point.

    fid = fopen( old_filespec );
    cac = textscan( fid, '%s', 'Delimiter','\n', 'CollectOutput',true );
    fclose( fid )
    fid = fopen( new_filespec, 'w' );
    for jj = 1 : insert_here
        fprintf( fid, '%s\n', cac{jj} );
    end
    fprintf( fid, '%s\n', new_line );
    for jj = insert_here+1 : length(cac)
        fprintf( fid, '%s\n', cac{jj} );
    end
    fclose( fid );

MATLAB: How to delete a specific line from text file

You might notice that the below is not a nice little 3 or 5 line program. That is because the operating systems that MATLAB is supported on do not offer any method of deleting bytes in the middle of a file. The only real option is to copy the wanted text to another file and rename the files around.

Some of what is in this code is error checking and making sure that there is always an intact version of the file. If something goes wrong, you don't want to end up with a corrupted file. Always keep a backup version until you know the the deletion did what you wanted (and only what you wanted)

first_line_to_delete = 3;
num_lines_to_delete = 1;
infilename = 'YourFile.txt';
[pathstr, file, ext] = fileparts(infilename);
backfile = fullfile(pathstr, [file '.bak']);
if strcmp(infilename, backfile)
  error('I refuse to edit a backup file! Nothing has been changed.');
end
outfile = tempfile;   %a temporary file in TMP directory
fin = fopen(infilename, 'r');
if fin < 0; error('Input file does not exist'); end 
fout = fopen(tfile, 'w');
if fout < 0
  fclose(fin);
  error('Could not open temporary output file');
end
%read lines before the one to be deleted and write them to output
for K = 1 : first_line_to_delete - 1;
  inline = fgets(fin);
  if ~ischar(inline); break; end;  %end of file?
  fwrite(fout, inline);
end
for K = 1 : num_lines_to_delete
  if ~ischar(inline); break; end   %in case EOF
  inline = fgets(fin);   %and do nothing with it
end
%copy all remaining input lines to output file
while ischar(inline)
  inline = fgets(fin);
  if ischar(inline)   %not if we hit EOF
    fwrite(fout, inline);
  end
end
fclose(fin);
fclose(fout);
%M'Kay, we did the copying and have a file with the desired
%result. Now put it in the proper place
status = movefile(infilename, backfile);
if ~status
  if strcmp(infilename, backfile)
    fprintf(2, 'Good thing your programmer is paranoid about people overriding\nsanity checks, because something went wrong and you nearly lost your file!\n');
  else
    delete(backfile);
  end
  error('Could not rename file to .bak, file left untouched');
else
  status = movefile(outfile, infilename);
  if ~status
    error( ['Could not rename temp file to original name, original moved to ', backfile]);
  end
end
