% Write a function called “makemat” that will receive two row vectors as
% input arguments, and from them create and return a matrix with two rows.
% You may not assume that the length of the vectors is known. Also, the
% vectors may be of different lengths. If that is the case, add 0’s to the
% end of one vector first to make it as long as the other.
% For example, a call to the function might be:
% >>makemat(1:4, 2:7)
% ans =
% 1 2 3 4 0 0
% 2 3 4 5 6 7
lv=length(v);
lw=length(w);
if lv<lw
    v(lw)=0;
elseif lv>lw
    w(lv)=0;
end
A=[v;w];
