You may rotate the image instead of the axes
B = imrotate(A,angle)
or refers to the documentation below

You can create a hgtranform and parent the axes to that transform. Then you create a transformation matrix and apply it against the hgtransform . maketform() is useful for creating the transformation matrix.
Note: if you rotate an image out of the x/y plane even a little, it will mostly disappear almost immediately, leaving only lines for the edges. This is because in MATLAB, image objects are 2D not 3D, so they have no thickness. If you need to be able to rotate an image out of the x/y plane then you can use texture mapping. The warp() function can be useful for this purpose.
