About the Matrix Plot
The image on the previous page is a
Mathematica
matrix plot of a random 9-by-9 matrix with integer
elements between -9 and 9.
Random matrices are used throughout the book where matrix forms are required to illustrate
concepts, properties, or calculations, but where the numerical content of the illustrations is largely
irrelevant.
The presented image shows how matrix forms can be visualized as two-dimensional blocks of color or
shades of gray.
MatrixForm[A
=
RandomInteger[{-− 9, 9},
{9,
9}]]
