could anyone help me to overcome the error in the following code.

code:

A=[ 0.7684    0.0120;
    0.5333    0.9666;
    0.0684    0.8322;
    0.1996    0.4453]
B=[0.6399    0.8965]
 if size(A)>size(B)
     A=A(size(B,1),:)
     social=B-A
 else
        [jj,kk]=size(A)
        [jjj,kkk]=size(B)
        zz=zeros(jjj,kkk)
        zz(1:jj,1:kk)=A   
        social=B-zz
 end

when i run the code i am getting error stating Error using -

Matrix dimensions must agree.

Error in line social=B-zz

Could anyone help me to execute the code.

This is not what I meant. Why didn't you comment on my answer? Then I might have seen this earlier. I'll close this question and edit my previous answers to clarify. Please comment there if you need clarification.
