Hello!!
I have a vector composed only for the numbers 1 and 0, like this:
A = [ 0 1 1 0 1 0 ];
I want to know the index of the last non-zero (1), that is 5 in this case: A(5).
Can someone help me?
Thank you!

You can check the doc for find: the k = find(X,n,direction) syntax should work for you.
k = find(A,1,'last');
