%% Return Both Matching and Nonmatching Substrings
% Capture parts of a character vector that match a regular expression using the 'match' keyword, and the remaining parts that do not match using the 'split' keyword.

str = 'She sells sea shells by the seashore.';
expression = '[Ss]h.';
[match,noMatch] = regexp(str,expression,'match','split')

% The regular expression '[Ss]h.' specifies that:
% S or s is the first character.
% h is the second character.
% The third character can be anything, including a space, as indicated by the dot (.).
% When the first (or last) character in a character vector matches a regular expression, the first (or last) return value from the 'split' keyword is an empty character vector.
%
% Optionally, reassemble the original character vector from the substrings.

combinedStr = strjoin(noMatch,match)
