Add new column a vector.

Hi everyone. I have some vector for example x=[0;0;2;2;1;0;0;2;0]. How can I add a new vector (for example y=[43;43;34;34;34]) to a second column of vector x, so it becomes x=[0;0;2;2;1;0;0;2;0 43;43;34;34;34]?

"x=[0;0;2;2;1;0;0;2;0 43;43;34;34;34]" is not a valid Matlab array. What size do you want for "x"? How do you want to handle the different lengths? The result must be rectangular.

I don't know the size of matrix x. On each iteration I need to add a new number in the second column.

x = [0;0;2;2;1;0;0;2;0];
y = [43;43;34;34;34];
Combined{1} = x;
Combined{2} = y;
You need to use cells {} in order to store vectors of different sizes in one array.

x = [0 0 2 2 1 0 0 2 0]';
y = [43 43 34 34 34 0 0 0 0]'; % Must be of same length
You could either
cat(2, x, y)
or simply
ans = [x y]
