Let's say the column matrix is:

A =

2

6

7

3

8

3

2

9

7

5

4

1

And I need to obtain final result as

A =

2 6

7 3

8 3

2 9

7 5

4 1

Can I know the way to split in this way?

How shall the matrix be formed when there are odd number of elements? Is there a way to make it even by putting zero for the last element? Lets say: A = [2 6 7 3 8 3 2 9 7 5 4]. How can I obtain

B = 6×2

2 6

7 3

8 3

2 9

7 5

4 0

That depends on the size you want to arrange -

%For a 2D array, define atleast one dimension
ncol = 2;
A = [2 6 7 3 8 3 2 9 7 5 4];
%Convert to column vector
A = A(:);
%Add required zeros
A = [A;zeros(1,rem(numel(A),ncol))];
B = reshape(A,ncol,[])'
B = 6×2
     2     6
     7     3
     8     3
     2     9
     7     5
     4     0
