image rotation with equations?
显示 更早的评论
xrot = x*cos(θ) − y*sin(θ)
yrot = x*sin(θ) + y*cos(θ)
hold for images as well. can i rotate image with them?

Yes, but you will encounter the same limitations as with imrotate(), that you will need to end up with a rectangular grid that the rotated image takes up part of. image() and imagesc() and imshow() can only deal with horizontally and vertically aligned matrices.
You should have a look at hgtransform()

You could, when you incorporate them into imtransform(). But it would be easier just to use imrotate().
