A=[1 2
3 4
5 6];
B=[1 2];
A = repmat(B,size(A,1),1)
or
A = B .* ones(size(A))

when i used the command line A = repmat(B,size(A,1),1),it gives the following result A=[1 2;
1 2;
1 2]
IS it possible to change the rows of A one by one
First A=[1 2;
1 2;
5 6]
then A=[1 2;
1 2;
1 2]
Could you please help me on this.

That could be done in a loop, though it's not clear why this would be beneficial.
A=[1 2
3 4
5 6];
B=[1 2];
for i = 1:size(A,1)
A(i,:) = B;
end
Is that what you're looking for?
