I have this code using the idea from this post Vector manipulation by changing order or numbers in a vector. .
xcor = input('Input x coordinates vector transposed.')
%enter the cooordinates [ (numbers spaced) ]'
xcor_p1 = [xcor;xcor(1)]
xcor_p2 = [circshift(xcor_p1,[0 -1])]
e.g If the
xcor = [4 6 2]'
inputed I get
xcor_p1 = [4 6 2 4] '
as I need but Matlab generates
xcor_p2 = [4 6 2 4] '
I need
xcor_p2 = [6 2 4 4]'
as in the case in the with a and b from Vector manipulation by changing order or numbers in a vector. . What has gone wrong here?

Giuseppe, use
xcor = [4 6 2];
xcor_p1 = [xcor xcor(1)];
xcor_p2 = [circshift(xcor_p1,[0 -1])]'
