Question
(a) Create an image which look like the image shown below. Print out your Matlab code and show
your output image.
Useful Matlab command: meshgrid. Recall that the equation of a disk centered at (xo, yo) with
radius r is (x − x)² + (y − yo)² ≤ r².
1
(b) Write a Matlab code to rotate the image you created 45° counterclockwise about the center
of the image. Print out your Matlab code and show your output image. Don't use the Matlab
command "imrotate". You may use "interp2" for interpolations.
