Convert Strings into vectors of binary numbers

I need to convert utterance strings into vectors where each dimension of the vector represents a unique word, while reading the script from an m.file. So for example if I have, out='hello' 'my' 'name' 'is' 'sam'. I want a vector with binary numbers where hello is true and everything else is false.
Solution would be output=[1,0,0,0] How can I do this? Here is what I have so far
fid=fopen('sw4325.m')
>> firstline=fgets(fid);
>> sprintf(firstline);
>> splitstring=textscan(ans, '%s');
>> out=splitstring{:};

I do not get it. Do you want STRCMP?
str = {'hello' 'my' 'name' 'is' 'sam'};
match = strcmp('hello', str);

I mean turn the strings into a vector of binary numbers so hello my name is sam would become [1,0,0,0,0] if hello is in the string. I have to do this for the whole file so, I'll get vectors with 1s and 0s where the 1s are for when the string 'hello' holds true
Have you actually tried Jan's code? It does exactly what you ask for, as far as I understand it.
Thank Jan, your code does work for strings. But I have my data in a cell of strings, and it won't work for it. Here is my code f=fopen(‘hello.m’) firstline=fgets(f) sprint(firstline) splitstring=textscan(ans, ‘%s’) out=splitstring{:}
Do I need to convert this into strings first? If so, how do I do that, I'm new to Matlab, and I usually use Java so it's a little confusing
Sorry, I do not understand which data are strings and which are cell strings. Using ans directly is prone to errors. Better split the string explicitly, e.g. out = regexp(firstline, ' ', 'split'). And then please explain again the type of the inputs. Either strcmp or ismember should solve the problem.
Yes it works, thank you so much.
