Calculate difference between successive vector values.

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)

This is much simpler and faster than A(2:end) - A(1:end-1). +1

Brilliant, thank you!

Is there any way to solve this problem using colon operator? Thanks!

[Voss]

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)

Was looking for a function that did this, thanks!!!
