Hi
I have text file that includes a register with personnumbers and names of peoples. I want to be able to edit that textfile by giving the code the name as a string input, and the code deletes the corresponding row to that name.
I have looked around, but I can't find any good example for this. Thank you for your help.
Regards

Look at the help for fgetl(). Just open the file, read line by line, for each line, use strfind() or strcmpi() to check the line against your template, and if it's not the template, write it out to another file. Then you can delete the first file and rename the output file the same as your original input file. Come back with your code if you still have problems, but at least give it a try yourself - like I said, the help has sample code for you.

Which one is the line that you don't want? Did you see this in the help:
TF = strcmpi(string,string) comparestwo strings for equality, ignoring any differences in letter case.The strings are considered to be equal if the size and content ofeach are the same. The function returns a scalar logical 1 for equality,or scalar logical 0 for inequality.
So did you try something like
if ~strcmpi(tline, 'Cichowski, Thomas 720114')
% Write to output as long as it's not the bad line.
fprintf(fid_Output, '%s', tline);
end
