Selecting words in MATLAB

I am trying to code a MATLAB program where I have to select a word from a group of 150 words divided into three groups of 50 words each. I know I need to apply some sorting and searching, but I don't know how to go about it in MATLAB.

Sorry for the delay in replying. So in Matt's example below, if the eye responses are {left, right, both}, then the program must form a phrase with one word from A followed by one word from B followed by one word from C?
If I understand you right, the computer must decide which of 'Help wow rent', 'Keep her true', etc., is meant by the user. In your problem, there are 50 words/phrases per group and therefore 50^3 possible combinations.

You don't say how the words are divided, or even what kind of selection is to be made. However, I will assume you have three cell arrays A,B,C. Like in this example, use RAND.
>> A = {'Help';'Keep';'love'};
>> B = {'wow';'her';'now'};
>> C = {'true';'sleep';'rent'};
>> word1 = A{ceil(rand*3)}
word1 =
love
>> word2 = B{ceil(rand*3)}
word2 =
wow
>> word3 = C{ceil(rand*3)}
word3 =
sleep
>>

What defines a "meaningful sentence"? Can it be represented by some logic? Then you can program it just like what Matt did, except you would replace "ceil(rand*3)" with the appropriate logic.

If your goal is to search for a given string in a cell array, you can use strcmp.

I understand what the goal of your application is, but it's still not clear on the specifics of how and what your want to "sort and search". In your comment above, you mention "first third", "second third", and "last third". With 150 words, that's pretty straight-forward:
firstThird = allWords(1:50);
secondThird = allWords(51:100);
lastThird = allWords(101:150);
For sorting, use the function sort. For searching for a specific word in a cell array, use the functions strcmp or strcmpi.
