I have a matrix.

A=[1 2 3 4 5 6 7 8]

I want to separate the alternate elemets from the array.

I tried to do this,

N=[1 2 3 4 5 6 7 8];

Th1=zeros(4,0);

Th2=zeros(4,0);

for i=1:1:8

if mod(i,2)==0;

Th1=N(i);

else

Th2=N(i);

end

I am sure solution must be very simple. But, the code seems to save only the last values. Any help?

A = [1,2,3,4,5,6,7,8];
X = A(1:2:end)
X = 1×4
     1     3     5     7
Y = A(2:2:end)
Y = 1×4
     2     4     6     8
