Test if any element of a vector equals 1

Question

I am trying to use the find operator in Matlab as a boolean and Im wondering if its even possible, if so how so?

This is what I am trying to do

//If The second column in X contains a 1, do something
if(find(X(:,2) == 1) == true)
//do something

Answer 1

I think you're looking for the any function:

if(any(X(:,2) == 1))
//do something

You could achieve something like this using find, I wouldn't recommend it though. Here is one option:

if(numel(find(X(:,2) == 1)) > 0)
