Examples
Here are some examples of how you can use these functions.
Creating a Magic Square Matrix. A magic square is a matrix in which
the sum of the elements in each column, or each row, or each main diagonal
is the same. To create a 5-by-5 magic square matrix, use the magic function
as shown.
A = magic(5)
A =
17 24 1 8 15
23 5 7 14 16
4 6 13 20 22
10 12 19 21 3
11 18 25 2 9
Note that the elements of each row, each column, and each main diagonal
add up to the same value: 65.
Creating a Random Matrix. The rand function creates a matrix or array
with elements uniformly distributed between zero and one. This example
multiplies each element by 20:
A = rand(5) * 20
A =
19.0026 15.2419 12.3086 8.1141 1.1578
4.6228 9.1294 15.8387 18.7094 7.0574
12.1369 0.3701 18.4363 18.3381 16.2633
9.7196 16.4281 14.7641 8.2054 0.1972
17.8260 8.8941 3.5253 17.8730 2.7778
The sequence of numbers produced by rand is determined by the internal
state of the generator. Setting the generator to the same fixed state enables
you to repeat computations. Examples in this documentation that use the
