这是伯克里wavelet transforms一书中的例子的代码

function rr = rright(v,n)
%rr = rright(array,n) will rotate the given 
%array n steps to the right and pass the output
%to the array rr.
%
%The input variables are
%array: The input array
%n    : This gives the amount of rotation in terms of
%       number if samples.
