Re: Rotating NxN matrix by arbitrary angle

Hi Nevzat,
ROOT has TMatrix class which does matrix operations. You can write a small program to rotate your matrix using it. I am not sure if someone has already written a custom library to do other transformations -- but here is the link to get started:
