amr - strfind returns the starting index of the pattern within the string so it won't necessarily return one. And this function will return an empty matrix if the pattern cannot be found in the string. If you want to return a one (true) or zero (false) then you could wrap this function within an anonymous function. Something like
isPatternInString = @(string,pattern)~isempty(strfind(string,pattern));
You could then call the above in place of strfind as
string = 'amr';
pattern = 'xyz';
if isPatternInString(string,pattern)
fprintf('pattern is in string!\n');
else
fprintf('pattern is not in string!\n');
end
We pass the string and pattern into the anonymous function and rely on it to determine if the pattern is in the string: if the result of strfind is an empty array, then isempty returns true and we apply the logical not (with the tilde) to get the desired answer of 0 (false).
