Creating a vector from a set of coordinates

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,:)

If I have N number of x and y coordinates, how do I index each pair of coorditnates from 1 to N and store these indices in a vector?

There is no need to "store the indices". length(x), numel(x) or size(x) could return the size information if that is what you want.

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
