I am new to MATLAB. To improve my skills I am practicing with simple problems. One problem is extracting even and odd numbers from a vector.For e.g. I wrote this code to extract odd and even numbers from a vector.
A=linspace(1,1000,1000);
Odd=[];
Even=[];
for i=1:length(A)
if rem(A(i),2)~=0;
Odd=[Odd;A(i)];
else
Even=[Even;A(i)];
end
end
A colleague pointed out that there is an even easier way of doing this..(there could be many)
Odd=A(rem(A(:),2)~=0);
Even=A(rem(A(:),2)==0);
I don't understand how this code works. The part rem(A(:),2)~=0 gives a logical array. How does index of logical array ultimately give odd and even numbers?
