Hi, this for statement
for string = ['=A=', '=B=', '=C=']
[starts, ends] = regexp(line, string);
the strings read as single '=' character in regexp ; as = is not a special character according to regexp, there is no need to precede it with \, as in '\=A\=' ? I tried some solutions using additional variables to represent those strings, or sprintf, but it didn't work ... Can somebody help me ? Thank you

there should be an accept answer somewhere
Come to think of it, I don't know exactly how you build your pattern there and if it really is a simple pattern as you wrote here, but a single pattern can easily cope with all three letters
regexp(line, '=[ABC]=')

The best thing would be for TADA to write his answer as an actual answer so that pierre can accept it. You can't accept comments.
The question should not be closed as it would no longer be visible. It contains useful information.

you will probably want to switch from a vector to a cell array of character vectors
patterns = {'=A=' '=B=' '=C='};
for i = 1:length(patterns)
[starts, ends] = regexp(line, patterns{i});
end
or better yet like Stephen Cobeldick mentioned, send the cell array over to regexp
patterns = {'=A=' '=B=' '=C='};
[starts, ends] = regexp(line, patterns);
or just put it all in a single pattern
[starts, ends] = regexp(line, '=[ABC]=');
