how to split data

rx = [1

3

4

5

6

7

8

9

2

6]

Please how can I divide this data above to half to get x and y

x = [ 1 3 4 5 6 ]

y = [ 7 8 9 2 6]

thanks

What if it has 11 elements then ??

you ignore the last element

Why not just use basic MATLAB indexing?:

>> x = rx(1:5)
x =
   1
   3
   4
   5
   6

>> y = rx(6:10)
y =
   7
   8
   9
   2
   6

If you really want the output to be horizontal, simply add a transpose:

>> x = rx(1:5).'
x =
   1   3   4   5   6

Another option:

M = reshape(rx(1:2*fix(numel(rx)/2)), fix(numel(rx)/2), []);
x = M(:,1)'
y = M(:,2)'

This automatically discards elements at the end that result in the length of ‘rx’ not being a multiple of 2, and produces the same result if ‘rx’ is a row or column vector. It only works correctly if ‘rx’ is a vector.
