but... the above solutions (seems) to work...
% use BS char instead of '<'...

s='Take meX< home, cas<<ountry rosdXX<<<<ad.';
bs=char(8);
s=strrep(s,'<',bs);
ix1=strfind(s,bs);
ss='';
while true
ss=regexprep(s,['(\w{1,1}',bs,')'],'');
if isequal(ss,s)
break;
end
s=ss;
end
ix2=strfind(s,bs);
ix1
ix2
%{
% ix1 =
9 20 21 35 36 37 38
% ix2 =
[]
%}

Of course this works. And it is easy to understand, modify and debug (if it would have a bug).
I'm just disappointed, that the simple FPRINTF *can* perform the conversion when printing to the command line, but I cannot catch the result to a string again.

but jan...
you simply cannot have if all:
- either germany wins a great(!) third...
- or ML provides a solution to this conundrum...

now, let's see what paul did: he/she/most likely it(!) voted for #1...

How about a drunk and angry armadillo with a hatred of multiple lines?



% DATA
STR = 'Take me homeuuu<<<, cas<<ountry rosd<<ad.'

% ENGINE
STR(cell2mat(cellfun(@(x)x(1)-diff(x)-1:x(2),regexp(STR,'(<)+','tokenExtents'),'Un',0))) = ''
