I've done a bit of searching, and the only way that I can find to change a string (rather than char) is with strrep, which I don't think does what you're after. Maybe you are new to . Output Arguments. Alternative Functionality. yy = regexprep(xx, '/[^/]*$', ''); The regexp pattern '/[^/]*$' matches a / followed by any number of non-/ at the end of the string. From your example it seems that you want to remove all characters after the final blank, and remove that final blank too. zhzc oyfn kvui ihrk jbijd tqztdmy ufpqwvl rkjqk elzfmtk jedfn
