search for: h12345abcdefgh12345abcdefg

...et analysis experts have implemented periodic boundary conditions for signals. I need to implement a circular buffer. Something like: "12345abcdefgh12345abcdefgh" so that at each step the riightmost element is moved to the leftmost index and everything else is properly shifted: "h12345abcdefgh12345abcdefg", "gh12345abcdefgh12345abcdef", .... My implementation (still debugging) seems to start working but is terribly clumsy. I am sure that some expert can suggest a more elegant solution, Thank you. Maura tutti i telefonini TIM!
