wrapping

I have a wrapped date. and then I use a commend "unwrap" in order to unwrapped data.

After unwrapping, I modified unwrapped data.

I want to get wrapped data again in order to see what happened is in data.

how do i wrap after taking "unwrapping original" data.

You could save the changes when you unwrap and then reverse them:

pw = unwrap(pold);
pdiff = pw-pold;
... % change pw here
pnew = pw-pdiff;
