How do I divide a vector into two vectors of unequal length so that the first vector contains 2/3 ,and the other contains1/3

Example

A=[1 2 3 4 5 6]

result

B=[ 1 2 3 4 ]

C=[6 7]

I assume you mean C = [5,6], because A does not contain a 7.

That's right, thank you, sir

A = [1 2 3 4 5 6];
idx = ceil(numel(A) * 2 / 3);
B = A(1:idx)
B = 1×4
     1     2     3     4
C = A(idx + 1:end)
C = 1×2
     5     6
