Very tricky:Manipulation with complex array

1 view (last 30 days)
I need to write a m.file function for this.
For example
array X = [4, 1, 1, 3, 8, 12], I need to make the array which will contain bold ones as well Y = [4, 1, 5, 1, 3, 4, 8, 12, 20].

Following @Paul suggestion
% original vector
X = [4, 1, 1, 3, 8, 12];
% reshape to have 2xN vector
W = reshape(X,2,[]);
% calculate the sum
S = sum(W,1);
% concat the vector and reshape
Y = reshape([W; S],1,[])
Y = 1×9
4 1 5 1 3 4 8 12 20

Because this tasks want from me to learn logic of the Matlab.I know its absolutely better like this.
But maybe i will get problem like this and i will be stucked if i dont know some function.
Write a m.file which is asking to enter array X (integer numbers),which will make a new array Y .Elements of the array Y are sum from even digits of elements array X. If some element of array X is not inteneger,make a comment about error.
For example X = [81, 19, 102, 22, 12, 21] Y = [8, 0, 2, 4, 2, 2]
And I will need to use the loop to see is there a even digit in every number
