Comparing Two String Arrays

Hello,

I am trying to compare two string arrays to each other to see if any of the elements in one string array are in the other string array. I assumed the best approach was to use "any" and "strcmp".

This is my code. I was able to make it work if i placed "dad" as the first elment in 'stringMe'. However when I set the first element in stringMe to "mom", it did not work. Any suggestions or advice are greatly appreciated.

string = ["dad" "hey" "mom"];
stringMe= ["mom" "bob" "ted"];
if any(strcmp(string,stringMe))
    disp('hello');
end

Try intersect():

string = ["dad" "hey" "mom"];
stringMe= ["mom" "bob" "ted"];
inBoth = intersect(string, stringMe)
if ~isempty(inBoth)
    message = sprintf('"%s" is in both', inBoth);
	uiwait(helpdlg(message));
end
