MATLAB: How to do crossover between two matrices.

Question

Suppose we have two matrices A and B. Now we randomly select the number of a rows which corresponds to a non-zero row and exchanges the corresponding rows between two matrices.

For example

A =

    [0     0     0     1     0     0     0     0     0     0
     0     0     0     0     0     0     0     1     0     0
     0     0     0     0     0     1     0     0     0     0
     0     0     0     0     0     0     0     0     0     0
     0     0     0     0     0     0     0     0     0     0]
 B =[0     0     0     0     1     0     0     0     0     0
     0     0     1     0     0     0     0     0     0     0
     0     0     0     0     0     0     0     0     1     0
     0     0     0     0     0     0     0     0     0     0
     0     0     0     0     0     0     1     0     0     0]

Now suppose randomly we selected row number 1 and 3. so we exchange these rows between matrices A and B and the answer matrices are

C =

    [0     0     0     0     1     0     0     0     0     0
     0     0     0     0     0     0     0     1     0     0
     0     0     0     0     0     0     0     0     1     0
     0     0     0     0     0     0     0     0     0     0
     0     0     0     0     0     0     0     0     0     0]
 D =[0     0     0     1     0     0     0     0     0     0
     0     0     1     0     0     0     0     0     0     0
     0     0     0     0     0     1     0     0     0     0
     0     0     0     0     0     0     0     0     0     0
     0     0     0     0     0     0     1     0     0     0]

Answer 1

ii = [1,3]
E = cat(3,A,B);
E(ii,:,:) = E(ii,:,end:-1:1);
CC = num2cell(E,[1,2]);
[C,D] = CC{:};
