I have a code that I am running and wish to write a text file with time and date and name of the input file i have used every time the code is run.
I have struggled to this in a form in which can be added to each time it is run.
Any help would be appreciated, thanks

So you want a single log file and each time you run your code you want to append that info to the file. You dont want a new file each time you run.
Are you having trouble figuring out how write to a file or are you just looking for the 'a+' permissions option of the fopen command? That willlet you append lines to the end of an existing file.

I assume that you want to append the execution information (time, date and name of the input file) of your code each time whenever you execute it in a single file. Following is the sample code to be added in your source code which may serve your purpose.
fid=fopen('log.txt','a+');
time = datestr(clock,'YYYY/mm/dd HH:MM:SS:FFF');
inputFile='example';
fprintf(fid,'\n%s %s',time,inputFile);
fclose(fid);
