a=[11 23 165 200 213];
a1=de2bi(a,8,'left-msb');
out1=[];
for i=1:length(a)
    
     k= mat2cell(a1(i,:),1,[4,4]);
     k1=bi2de(cell2mat(k(1)))
     k2=bi2de(cell2mat(k(2)))
     out1(i,:)=[k2 k1]
end
output
out1 =
    13     0
    14     8
    10     5
     1     3
    10    11
a1 is 
0	0	0	0	1	0	1	1
0	0	0	1	0	1	1	1
1	0	1	0	0	1	0	1
1	1	0	0	1	0	0	0
1	1	0	1	0	1	0	1
k1 and k2 are not in left-msb

I am facing two problems.

1) since left-msb is used in 2nd line(no problem here) but when I split it and convert it into decimals I am getting half left-msb and half right-msb.

2) Secon I want to write the output in a single row like [13 0 14 8 10 5 1 3 10 11].

2.

%to convert out1 to row form
out1 = reshape(out1.', 1, []);

Here's a guess at what result you want to see for problem 1:

a=[11 23 165 200 213];
a1=de2bi(a,8,'left-msb');
out1=[];
for i=1:length(a)
    k= mat2cell(a1(i,:),1,[4,4]);
    k1=bi2de(cell2mat(k(1)),'left-msb'); % make k1 and k2 left-msb like a1 is?
    k2=bi2de(cell2mat(k(2)),'left-msb');
    out1(i,:)=[k2 k1];
end
out1 = reshape(out1.',1,[])
out1 = 1×10
    11     0     7     1     5    10     8    12     5    13

Another way to do the same:

a=[11 23 165 200 213];
a1 = dec2bin(a,8) - '0';
n = numel(a);
out1 = zeros(n,2);
for i = 1:n
    out1(i,2) = polyval(a1(i,1:4),2);
    out1(i,1) = polyval(a1(i,5:8),2);
end
out1 = reshape(out1.',1,[])
out1 = 1×10
    11     0     7     1     5    10     8    12     5    13
