I have two vectors of different sizes: A=5000x1 and B=86000x1. They both represent time in seconds, but A shows important timestamps while B shows all seconds in my observation window.

I was wondering how I can calculate a binary Result vector where 1 will mark each of the seconds in B that were stamped in A, and 0 will mark all the remaining seconds. I realised A could also work as a vector showing indexes, since B is a continuous vector 1:86000, if that helps.

I am struggling with this problem, that doesn't look very complex but it's eating my brain. Thanks!

I Actually solved this question already. I have created a 86000x1 vector of zeros and tranformed all the indexes stated in vector A into ones. It was easy. Thanks anyway.
