hi there,
I have an array lets say
A=[10 9 10; 1 2 3; 4 5 6]
How can create an array like this?
B=[10-1 9-2 10-3;10-1-4 9-2-5 10-3-6]
thanks in advance!

If I understand correctly what you are asking, this will work:
A=[10 9 10; 1 2 3; 4 5 6]
B = cumsum(-A(2:end,:))+A(1,:)
A =
10 9 10
1 2 3
4 5 6
B =
9 7 7
5 2 1
