Uniform crossover with boolean population

I have this code in matlab to find 'uniform crossover' for the same vector W

   W=[12,5,6,78,9,3];
   %Parameters
   N=2;
   G=10;
   Pop=round(rand([N,G]));
   %%Uniform crossover
   id=logical(round(rand(size(pop)))); %index of genome from W2
   Pop2=Pop(W(1:2:end),:);%Set Pop2=Pop W1
   P2A=Pop(W(2:2:end),:);%Assemble Pop2 W2
   Pop2(id)=P2A(id);%combine W1 and W2

I got an error message at the last part of the code : Index Exceeds Matrix Dimensions. How can i solve the error?

Pop is a different variable than pop. id will be the same size as pop.

Pop2 and P2A are formed by taking 3 subset rows from Pop. You then try to index them at id which is the full size of pop. That will fail unless pop is 3 or fewer rows and has no more columns than Pop does.
