The most important initial concept to understand in MATLAB is that MATLAB is heavily based on the concept of arrays and matrices.

In MATLAB you can define a one-dimensional array explicitly
using the syntax **a=[1., 2., 3.]** . The rectangular brackets tell
MATLAB you wish to make an array. A shorthand
notation is **a=1:3**.

To define a 3 by 3 matrix, you can similarly use
**mymatrix = [1., 2., 3.; 4., 5., 6.; 7., 8., 9.]**
Note that commas separate the columns, and the rows are separated
by semicolons.
The 2,3 element of the is matrix is accessed as
**mymatrix(2,3)**.

Often it is convenient to have MATLAB create a list for you.
To create 30 points between 0 and 2 , one can say
**pointlist=linspace(0, 2*pi, 30)**.
