If I have a set of coordinates of:
x = [10.1, 5.4, 7.3, ...];
y = [2.3, 7.4, 8.8, ...];
How can I create a single vector that assigns each point to an integer such that index = [1 2 3 ...]. E.g. the point with index 1 has the coordinates of x(1), y(1)
Appreciate any help.

If you do:
r = [x(:),y(:)]; % (:) forms column-vectors of any-dimensional array.
Then you will find:
p1 = r(1,:)

You mean like this? There is really no need to do this. Please explain the need.
x = [10.1, 5.4, 7.3];
y = [2.3, 7.4, 8.8];
index=[x;y]';
index(1,:)
ans =
10.1000 2.3000
