    %% Select Text After Substring
% Create string arrays and select text that occurs after substrings.
%
% Create a string. Then create a new string that occurs after the substring
% |'quick '|. The |extractAfter| function selects the new text but does
% not include |'quick '| in the output.
str = string('The quick brown fox')

%%
newStr = extractAfter(str,'quick ')

%%
% Create a new string array from the elements of a string array. When you specify 
% different substrings as positions, they must be contained
% in a string array or a cell array that is the same size as the input string array.
str = string({'The quick brown fox jumps';'over the lazy dog'})

%%
newStr = extractAfter(str,{'quick ';'the '})
%%
% You also can specify one substring as a position that is applied to all
% elements of the input string array.
