Chapter 13, Problem 13.2P

To determine

To create:

The $3\times 3\left(\times 3\right)$ true color matrix by using the type uint8.

Answer to Problem 13.2P

Solution:

The script file is,

matrix = zeros(2, 2, 3);

%define the 3*3 true color matrix.

matrix(1, 1, 3) = 255;

matrix(1, 3, 3) = 255;

matrix(1, 2, 3) = 255;

matrix(2, 1, 3) = 255;

matrix(3, 3, 3) = 255;

matrix(2, 2, 3) = 255;

matrix(2, 2, 3) = 255;

matrix(3, 1, 3) = 255;

matrix(3, 2, 3) = 255;

matrix(2, 3, 1) = 255;

matrix = uint8(matrix);

image(matrix);

%create an image of a 3*3 true color matrix.

Explanation of Solution

A true color matrix is created of the order of $3\times 3$.

MATLAB Code:

matrix = zeros(2, 2, 3);

%define the 3*3 true color matrix.

matrix(1, 1, 3) = 255;

matrix(1, 3, 3) = 255;

matrix(1, 2, 3) = 255;

matrix(2, 1, 3) = 255;

matrix(3, 3, 3) = 255;

matrix(2, 2, 3) = 255;

matrix(2, 2, 3) = 255;

matrix(3, 1, 3) = 255;

matrix(3, 2, 3) = 255;

matrix(2, 3, 1) = 255;

matrix = uint8(matrix);

image(matrix);

%create an image of a 3*3 true color matrix.
