Hi all, Hopefully a straightforward question, but one that I'm struggling with. I have a vector and want to create a new vector whose values are equal to the difference between successive values from the previous vector. e.g A = [1,2,3,3,0] want B = [1,1,0,-3]
What is the simplest way of doing this? Many thanks in advance. Will

A=[1,2,3,3,0]
B=diff(A)

The method given in Jan's comment above uses the colon operator:
A = [1,2,3,3,0];
B = A(2:end) - A(1:end-1)
