finding a string with parentheses using regexp
显示 更早的评论
A={'5123(P)';'5123 ESP'} how can i search A to find the cell that has the '(P)' string?
find(~cellfun(@isempty,regexp(A,'(P)')));
is giving 1 & 2 as answer which is not correct since it should be 1 only

find(~cellfun(@isempty,regexp(A,'\(P\)')));
Explanation: parentheses are special characters in regular expressions, and need to be escaped to be treated as literal parentheses. Of course the documentation is the best place to learn how to to use regular expressions properly:
Alternatively you could simply use strfind instead of regexp:
find(~cellfun(@isempty,strfind(A,'(P)')))
