I/O operations How to delete a file if exist?

Hi, I have written a function in Matlab and want to write results in a text file, which will be stored in working directory. But, I want to delete the result file if already exist and write new results. How to achieve this? Any help most welcome. Thanks.

You can open the file directly in write mode

fh = fopen('ResultFile.txt','w');

If file already exists, this will over-write the all old contents of text file and you can write simply new contents. If the file not exist it will create a empty file. No need to manually check and delete file.

Still if you need check & delete option

if exist('ResultFile.txt', 'file')==2
  delete('ResultFile.txt');
end
