how to split data
显示 更早的评论
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

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.
