hello,

i'm wondering if it is possible to find a rotation matrix that does not rotate about the origin.

A and B shows the standard rotation of a square about the origin. C is a square not about the origin, if i apply the rotation matrix, i end up with D, however I'd like to end up with E.

If C had the coordinates c1 (-1,1) c2 (-1, 3), c3 (-3, 3), c4 (-3, 1). It would be a rotation about (-2, 2). Is this possible?

thanks
