MATLAB: Is there a more efficient way to omit certain characters from a string without using loops

beginnerMATLABregexprepstrrep

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?
