Let's start off by creating something simple, like a vector. Enter each
element of the vector (separated by a space) between brackets, and set it equal
to a variable. For example, to create the vector a, enter into the Matlab
command window (you can "copy" and "paste" from your browser into Matlab to make
it easy):
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.
