According to my understanding you want to arrange the odd and the even numbers from a 1-D matrix into a 2-D matrix but with a certain arrangement.
I have given a code according to your given number list but it can be modified according to the requirement.
a = 1:16;
b=zeros(4,4);
a_odd=zeros(1,16/2);
a_even=zeros(1,16/2);
x=1; y=1;
for i=1:16
if rem(a(i),2)==0
a_even(1,x)=a(i);
x=x+1;
else a_odd(1,y)=a(i);
y=y+1;
end
end
x=1; y=1;
for i=1:4
for j=1:4
if rem(i,2)==0
b(i,j)=a_even(x);
x=x+1;
else
b(i,j)=a_odd(y);
y=y+1;
end
end
end
disp(b);

you can do this with the reshape command:
a = (1:16)'
b = reshape(a, 4, [] )
