MATLAB: Calculating each elements of matrixs

matrix elements

Hi all I am a highschool student studying matlab
What i want is to prgramming C matrix if matrix A (nx2), matrix B (nx2)
C(1,:)=A(1,:)-B(1,:)
C(2,:)=A(2,:)-B(1,:)
C(3,:)=A(3,:)-B(1,:)
C(4,:)=A(4,:)-B(1,:)
             :
             :
C(n,:)=A(n,:)-B(1,:)
C(n+1,:)=A(n,:)-B(2,:)
C(n+2,:)=A(n,:)-B(2,:)
C(n+3,:)=A(n,:)-B(2,:)
C(N+4,:)=A(n,:)-B(2,:)
             :
             :
C(n*n,:)=A(n,:)-B(n,:)
I ve tried like
I=1;
J=1;
K=1;
C(I,:) = A(J,:)-B(K,:);
for J = J+1
    K = K+1
    I = I+1
end
But failed, I hope some of you might help me

C = reshape(bsxfun(@minus,A',permute(B',[1 3 2 ])),size(A,2),[])'
or
C =  reshape(bsxfun(@minus,permute(A,[1 3 2]),permute(B,[3 1 2 ])),[],2)
or
C =  reshape(bsxfun(@minus,reshape(A,size(A,1),1,[]),reshape(B,1,size(A,1),[])),[],2)
