execute this code:
x = 1:10 % create a vector with elements from 1...10
a = x(end) % access last element of vector and write to a
b = x(end-1) % access 2.last element of vector and write to b
c = x(1:5) % access elements 1...5
d = x(1:end) % access all elements
e = x(1:end-1) % access all elements but not the last one
f = x(1:end-3) % access all elements but not the last three
g = x(1:2:end) % access every second element
