Thread Subject: easy string manipolation

Sorry for the easy question...

I have some strings like these
dummy='a, b'
dummy='a ,b'
dummy='a b'
dummy='a,b'

first and second terms are separated by space OR/AND comma
I wish to separate first adn second term of the string

This is my solution
----
[first,second]=strtok(dummy,' ,')
idx=find (second==',' |isspace(second) );
second(idx)=[];

first
second
----
It works, but it is not easy to generalize for string with 'n' terms
Any hint ??

Thank you very much!!

well, this is messy and regexps would probably work well here, but...

rema = strrep(dummy,',',' ');
cnt = 0;
while ~isempty(rema)
cnt = cnt+1;
[element{cnt}, rema] = strtok(rema,' ');
end

OK! Thanks!
