Could anyone help me how to get the result as desired in the following code.

A=1:20;
while ~isempty(A)
B=reshape(A,[],2);
B(:,end)=B(end:-1:1,end);
for k=1:size(B,1)
C=B(k,:)
A=[];
end
end
The code executes and gives the following result
C = 1 20
C = 2 19
C = 3 18
C = 4 17
C = 5 16
C = 6 15
C = 7 14
C = 8 13
C = 9 12
C = 10 11
But I want to have the result in the following manner
C = 1 20 4 17 7 14 10 11
C = 2 19 5 16 8 13
C = 3 18 6 15 9 12
Could anyone please help me on this.

If you need those specific values to run something else, then there is not much point in coding the order. Just store as cells that you can use
C={[1 20 4 17 7 14 10 11],[2 19 5 16 8 13 ],[3 18 6 15 9 12]}
And then use them in your code like
for k=1:3
C{k}
% ...
%...
end

hello
after so guess work, I finally change the code to this
clc
A=1:20;
B=reshape(A,[],2);
B(:,end)=B(end:-1:1,end);
for ci = 1:3
C = [];
ind1 = ci:3:size(B,1);
for k=1:length(ind1)
ind2 = ci+(k-1)*3;
C = [C B(ind2,:)];
end
disp(C)
end
and this is the result , as expected :
1 20 4 17 7 14 10 11
2 19 5 16 8 13
3 18 6 15 9 12
maybe those 3 lines should be stored in 3 cells ?
