One way:
v = [0 0 1 1 1 ];
A = [v; circshift(v,[0 -1]); circshift(v,[0 -2])]

My pleasure!
Use a for loop. If all you want to do is to shift the columns as you described for each row, change my example code to the more generalised version:
v = [0 0 1 1 1 ];
nrows = 3;
for k1 = 1:nrows
A(k1,:) = circshift(v,[0 1-k1]);
end
Change v to the vector you want, and change the number of rows you want to create (denoted here as the value of the variable nrows) to create your matrix.
