That is, the NEW_DATA would be a column vector (based on a sine function) that would basically minimize the difference from DATA1-NEW_DATA. If so, can someone help with the steps involved. I tried looking online and it seems like I would create a new m.file, but don't even know where to begin.

Perhaps this example will help:
