I feel like there's an easy solution to this that I'm missing. I have an array of points, p(x,y,z,i), in which the first three components, x, y, and z, are a point in 3d space and the last component, i, is the number assigned to that point. I want to search through the array and find the vector with the highest y-value. How can I do this?

If I assume that p is an Nx4 array, then,
[~,row]=max(p(:,2));
result=p(row,1:3)
