    %% Test Start of String Against Multiple Patterns
% Create a string array that contains file names. Determine which file names 
% start with either |abstract| or |data|.
str = string({'abstract.docx','data.tar.gz','mycode.m','results.ptx'})

%%
pattern = {'abstract','data'};
TF = startsWith(str,pattern)

%%
% Display the strings that start with either |abstract| or |data|. Index back 
% into |str| using |TF|.
str(TF)
