could anyone help me to solve my question

As i am unable to get the answer i am asking it again.

I am having two matrices A=[0.6399 0.8965] and B=[ 0.7684 0.0120;

0.5333 0.9666;

0.0684 0.8322;

0.1996 0.4453]

of different sizes generated in my code.

when size(A) is lesser than size(B) i done with the following command line

code1:

        [jj,kk]=size(A)
        [jjj,kkk]=size(B)
        zz=zeros(jjj,kkk)
        zz(1:jj,1:kk)=A   
        C=B-zz

the code executes and gives me the result.

As A and B are generated by the code,sometimes size(A) is greater than size(B) so i have used the following command line

code2:

 A=A(size(B,1),:)
 social=B-A 

the code executes and gives me the result.

As i doesnt know whether size(A) is greater or lesser than size(B) i need to use the above code 1 and code 2 together by using if condition.

Could anyone help me how to use if condition with respect to code 1 and code 2.

You don't need if here. You can mix them as:

C = B; 
len_A = min(size(B,1),size(A,1));
C(1:len_A,:) = C(1:len_A,:) - A(1:len_A,:);
