Plot a binary value each time a number in vector A is also present in vector B.
显示 更早的评论
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!

Or you could use ismember,
result = ismember(B,A);
