tx and ty are translation. I think a and d are scale and b and c are some function of rotation. I have videos that are flipped and rotated using arbitrary matrices. How can I make them right-side-up ...

In this paper a new algorithm for reducing an arbitrary real square matrix to tri-diagonal form using real similarity transformations is described. The method is essentially a generalization of a ...

Integrable systems have long captured the attention of both mathematicians and physicists due to their rich structure and exact solvability. Within this framework, defects—localised irregularities or ...
