How to perform these matrix calculations?

Hi,

Q1: I have matriz z of size (101 97) and I want substract e.g., first row from second, then second from 3rd row and 3rd from 4rth row and so on... such that the new matrx will be of size (100 97). How can I do it in matlab?

Q2: I have a matrx T of size 100 97 and want make calculation as explaind in the figure below: i.e., new value column E is the value of D column plus cumsum of previous values E (as given in figure). I want to perform it on a whole matrix of size(100 97)?

See the diff and cumsum functions.
