Plot a figure in which there is an image that moves and rotates

I am going to plot a dynamic image (moving, rotating) within a MATLAB figure. How can I do that?

I know that for embedding an image in MATLAB i should use this code:

I = imread('image.jpg');

figure;

hold on;

image([-1 1],[1 -1],I);

How to draw the image by indicating its center position and its scale. How to move / rotate it?

Just have a loop over angles and inside the loop call imrotate() and imshow() and drawnow.

clc;
clearvars;
close all;
workspace;
fontSize = 33;
grayImage = imread('cameraman.tif');
for angle = 0 : 10 : 360
  rotatedImage = imrotate(grayImage, angle);
  imshow(rotatedImage);
  axis on;
  caption = sprintf('Angle = %.1f', angle);
  title(caption, 'FontSize', fontSize);
  % Enlarge figure to full screen.
  set(gcf, 'Units', 'Normalized', 'Outerposition', [0, 0, 1, 1]);
  drawnow;
  pause(.5);
end

Thank you for your sincere answer. How can I get rid of that black background that is added after using imrotate?

You might be able to edit imrotate.m to make the background be the same color of gray as the figure background. Or maybe you can modify the figure background to make it black. Or else just make a big "canvass" each time and paste the image in:

w = ceil(max([rows, columns]) * sqrt(2));
canvass = 128 * ones(w, w);
rotatedImage = imrotate(grayImage, angle);
binaryImage = rotatedImage > 0;
canvass(binaryImage) = rotatedImage(binaryImage);
