i want this mean filter without padding and padding by replication .here in my code i have done padding with 1
a = input('Please input the matrix like "[1, 2; 3, 4]":');
% mf= ones(3,3)
% meanA = mean(A(:))
a1= padarray(a,[1 1],1)
[m n]=size(a1);
c=zeros(size(a));
for i=2:(m-1)
for j =2:(n-1)
v=a1(i-1:i+1,j-1:j+1)
vrow= v(:)'
r= median(v(:));
c(i-1,j-1)=ceil(r)
end
end
what modification do i need for this?

If you want to pad by replication, use the 'replicate' flag with padarray(). If you want to do the filtering without padding, you'll need to adjust your indexing limits accordingly, and you'll need to truncate your filter window as you operate near the image edges. Obviously, that sort of complication is why it's simpler to just use padding.
