Thank you Stefan and Kevin. Awesome solutions that answer my question. However I actually made a mistake in posing my question. Let me attempt to ask my question again.
I have 5 vectors as such: a [2 4 6 7] b [1 3 9 2] c [2 4 5 6] d [6 1 3 8] e [4 8 2 1] and the output i want is this a1 [0 0 0 0] b1 [1 0 0 0] c1 [0 0 0 0] d1 [0 1 0 0] e1 [0 0 1 1] Now I'm not sure if it can be done in one swoop, or should be done in a loop. I was thinking a loop, but I'm having trouble thinking about it. I initially thought of creating a function that takes in 5 vectors and returns a single vector. So the first time its called it would return a1 [0 0 0 0] then call it again and return b1 [1 0 0 0] etc... I know it will repeat calculations however I couldn't come up with anything else. Thank you.
