Hello. I have to take out characters from a string. I am using strrep. :

newsf = strrep(sf, 'C', '');

newsf = strrep(newsf, 'R', ''); n ewsf = strrep(newsf, 'E', '');

newsf = strrep(newsf, 'P', ''); newsf = strrep(newsf, 'SQ', '');

   newsf = strrep(newsf, '1', '');
   newsf = strrep(newsf, '2', '');
   newsf = strrep(newsf, '3', '');
   newsf = strrep(newsf, '4', '');
etc

I have tried using ~= for the characters I want but it won't accept that. Thanks for your time

One way would be

newsf = regexprep(sf, '([CREP1-4]|SQ)', '') ;

but what does "etc" encompass?

Thank you sir, that's brilliant. Sorry, I meant the rest of possible numeric values. 0-9 worked, thanks again
