I have a single column of data that is n long and I want to be able to subtract the second row in that column by the first and have that pattern repeat. (third row subtracted by the second, fourth row subtracted by the thrid and so on).
Ex:
1
5
6
7
4
3
I would like to be able to have a code that does 5-1, 6-5, 7-6, 4-7, 4-3.
I am pretty new to MatLab so if I am using incorrect terminology or my question is confusing in any way please let me know.
