after five hours...
With plenty of possibly incorrect assumptions that I still have to verify:
1. For a positive definite matrix A:
AXA' = A'XA
where X is also a matrix
*EDIT: OH noes... hindi pwede to!!! --> (pag-asa: is A symmetric?) --> buti na lang symmetric daw ang A! :D
2. For all matrices: --> OK: http://www.ltcconline.net/greenl/courses/203/MatricesApps/inverse.htm
(A^-1)(B^-1) = (AB)^-1
3. For all matrices also:
ABA^-1 = B
* can't find web page on this. Maybe I can argue that the result of A is a scalar.

parang field demo lang
to all my fans, kung nahihirapan kayong hanapin ako, nasa gawing likod po ako, kita kapag sa rear view na camera yung point of view ng video. Ako yang pangatlo from the left sa initial frame.
