Most likely, you don't even understand what you are asking since it is very unlikely that a 468x1 binary array would make any sense. In any case, you need to explain what is the rule to convert your array to binary.
Here is one way to convert your array to a 468x1 binary array:
result = randi([0 1], size(yourarray);
Here is another way, probably more useful:
result = yourarray > 0;
Neither are probably what you're after but how are we to guess?
