How to split string on the last delimiter?

I am supposed to separate a string '[e-mail]' into three separate string 'abcdef', 'eng.abc', 'edu' using strsplit function. However, I don't know how to split the string at the last . delimiter instead of separate them into four strings using C = strsplit('[e-mail]',{'@','.'}). Please help, thanks!

Well, you've got to have some other rule that tells you to not consider one delimiter a delimiter at all...what is that rule? You'd have to start by separating out the domain from the address then parse off the last TLD (top-level domain) by searching for the last dot.

lastdot_pos = find(YourString == '.', 1, 'last');

Thank though, but this doesn't work because after finding the last delimiter, it is still the same '.' , which appeared twice in the string.

YourString = '[e-mail]';
lastdot_pos = find(YourString == '.', 1, 'last');
part12 = YourString(1 : lastdot_pos - 1);
part12cell = strsplit(part12, '@');
part1 = part12cell{1};
part2 = part12cell{2};
part3 = YourString(lastdot_pos+1 : end );

Alternative:

YourString = '[e-mail]';
part123cell = regexp(YourString, '@|\.(?=\w+$)', 'split');
part1 = part123cell{1};
part2 = part123cell{2};
part3 = part123cell{3};

Thank you very much!
