VECTORS

a = [1 2 3 4 5 6 9 8 7]
Matlab should return:

a =
   1 2 3 4 5 6 9 8 7

Let's say you want to create a vector with elements between 0 and 20 evenly spaced in increments of 2 (this method is frequently used to create a time vector):

t = 0:2:20

t =
   0 2 4 6 8 10 12 14 16 18 20

Manipulating vectors is almost as easy as creating them. First, suppose you would like to add 2 to each of the elements in vector 'a'. The equation for that looks like:

b = a + 2
b =
    3 4 5 6 7 8 11 10 9

Now suppose, you would like to add two vectors together. If the two vectors are the same length, it is easy. Simply add the two as shown below:

c = a + b
c =
    4 6 8 10 12 14 20 18 16

Subtraction of vectors of the same length works exactly the same way.
